1.0 Introduction

This Particular Performance Specifications and Parameters (PPSP) provides the requirements of the Overhead Catenary System (OCS) for the LRT Line 2 East Extension Project. This project will extend the current Line 2 by 3.93km. This PPSP shall be read in conjunction with the Conditions of Contract, General Specification and all related Employer’s Requirements. In the event of a conflict between the General Specification and the PPSP, the requirements of the PPSP shall prevail.

2.0 Description of the Existing System

The existing OCS consists of center poles and cantilever beams; typical drawing is included in Part Two (2), Section VI-3 of the Employer’s Requirements. Simple catenary systems with automatic-tension-balancers are used for the existing OCS, 1500VDC and double insulation. The main materials for the electrical conductors are:

• Tin-coated hard-drawn grooved trolley wire, 137mm² for contact wire; • Hard-drawn copper stranded conductor, 240mm² for mainline messenger wire; • Hard-drawn copper stranded conductor, 120mm² for out-of mainline messenger wire; and • 120mm² bare copper for jumper wire.

For the integration of the LRT Line 2 Extension with the existing OCS, a drawing contained in Part Two (2), Section VI-3 of the Employers Requirements shows the last section of the existing OCS. The existing mainline catenary consists of: a) A single messenger wire and a single contact wire located over each track, using center

poles.

b) Tension length, or a conductor length, approximately 1,600m maximum between automatic termination points.

c) The existing OCS utilizes balanced weight anchors so that the conductor tensions will

remain largely constant despite temperature variations.

d) Half-tension lengths, up to 800m long, using one fixed-end-termination and one automatic termination.

e) The approximate center point is stabilized by using a midpoint anchor assembly, which

also limits the effects due to a wire breakage or defilement in the tension length.

For the LRT Line 2 Extension Project the Contractor shall ensure that all onboard equipment is modified, updated as required to cater for the additional route information required for the LRT Line 2 extension. Additional ATO equipment, modifications shall also be necessary at the two new stations.

b) ATO controls the normal train operating functions including propulsion, coasting,

braking, and correct station stop location in accordance with track characteristics such as gradient and curvature, and performance of rolling stock. ATO information is exchanged at stations and any auto start location.

c) Train operation shall be performed by the ATO system. However, it will be required that a train operator starts the train in ATO by pressing a button. The ATO system drives the train from station to station smoothly and efficiently. It shall stop the train at the required platform position with a minimum of 99.98% accuracy and opens the train doors and the tolerance shall be within ± 1.0 meter.

d) ATO system shall fulfill the performance requirements that are required by the train operation plan especially the turn back operation at Masinag station.



e) The ATO wayside system transmits data by both loop coils and possibly transponders/ balises. The Contractor shall ensure the ATO system is compatible with that currently employed on the existing line.

8.3 Automatic Train Supervision (ATS) System

d) The Contractor shall submit all proposed alterations to software modules to the Employer for approval.

e) The ATS software shall be rigorously tested using formal methods of verification and validation in accordance with the relevant standards. The Contractor shall ensure operational and functionality of the ATS system remains similar or better to those of the existing facilities.

f) The ATS System enables operators to supervise and monitor the entire rail system from an OCC. The OCC shall be capable of directing all transit operations both in normal and perturbed conditions. Should a complete failure of the OCC occur, operations may be continued from LCW located at the main Microprocessor based interlocking System areas. The LCW shall be capable of performing and displaying the same features and functionality as the OCC workstations.

g) The existing ATS subsystem Local Area Network (LAN) architecture shall be extended to incorporate the additional two (2) stations and the respective equipment. The Contractor shall ensure the additional connections to the existing LAN system do not have a detrimental effect to the overall availability objectives. The system shall be capable of expansion with minimal modification to the operating and application software. The Contractor shall provide appropriate documentation to confirm this requirement.

h) The OCC and LCW which generate geographical representation of the transit system network and shall be modified to incorporate the additional control and monitoring functions as required by the LRT Line 2 East Extension Project. The existing display shall display pages incorporating an ergonomically designed user-friendly HMI, adopting Graphical User Interface (GUI) techniques in a windows driven or similar environment. The display shall be capable of displaying an overview of the system and of individual stations and Microprocessor based interlocking system areas.



i) The Visual Display Units (VDU) shall be capable of rapid change between the display pages. The Contractor shall indicate the response times for the following: • Request a change of display page; • To fully display the requested page; • To request operation of route setting or equipment; • To action the request; and • Confirmation to the operator that request is accepted and operation complete.

j) The total response time under worst-case conditions for a complete operation shall not be

greater than ten (10) seconds. The changing of display pages shall require a response time of not greater than two (2) seconds under worst-case conditions inclusive of the additional loading of the system with respect to the Line 2 East Extension Project requirements.

k) Workstation visual display units shall not be degraded by EMI and processor connections and shall be appropriately isolated to avoid spurious operation. All processors inclusive of memories shall not be corrupted by the loss or momentary interruption of power, and shall be capable of restarting upon restoration of power. Battery backup shall be supplied for all essential memories. The ATS shall be configured to ensure that availability requirements are fulfilled. Where redundant servers are used both the on-line and standby shall receive data in order that both are fully updated; only the on-line machine provides the output function. Changeover from the on-line machine to the standby shall be automatically achieved. However, this may also be performed manually.

8.4 Functional Requirements of the ATS

a) The ATS shall directly interface with the microprocessor-based Microprocessor based

interlocking system located within the OCC. The Contractor shall provide fully documented listings of all inputs and outputs.

b) The ATS should typically monitor the status of the signaling and train control functions

as indicated below:

• Track section occupation; • Route set including Automatic Route Setting (ARS) and Fleet Mode; • Turnout position; • Signal Aspects • Train describer; and • Alarm Handling.

c) Any failure of the above functions generates an alarm, which shall be displayed on the

operator’s workstation indicating the criticality of the malfunction, and also logged (inclusive of date and time) in hard copy form on a dedicated printer. All alarms shall be time and date stamped; this shall be derived from the master clock, to which the ATS must interface. Alarms may be grouped and shall be differentiated by the level of criticality. Critical alarms shall take preference over non-critical alarms and shall remain displayed until the associated problem has been rectified. Additionally, alarms shall be annunciated with an audible device, which shall require to be acknowledged by the



operator. The Contractor shall submit their proposed alarm detection and display philosophy for approval by the Engineer.

d) The operators shall be able to set and cancel routes manually using a pointing device

and/or a keyboard. However, to ensure that trains are not unnecessarily held due to the operator not setting the route, ARS is to be included. This allows routes to be automatically set in front of trains provided the train is scheduled and the route ahead is clear. Unscheduled trains will not invoke the ARS. The operator may also inhibit the ARS.

e) The ARS function automatically sets routes for trains based upon: • The position of trains as reported by the train describer; • The train number, in accordance with timetable; and • Destination information with respect to where the train will terminate and turn around.

f) ARS requests shall be tested for route availability by the Microprocessor based interlocking system prior to the request being successful or otherwise. The ARS may try several attempts to set the route if the first effort fails. However, the ARS is not capable of route canceling. The Contractor shall stipulate either the number of re-tries for ARS, or a pre-determined timeout should the route setting fail. The ARS shall be capable of junction and terminal management in order to avoid conflicts and potential delays to traffic.

g) Signals shall also be capable of operating in “Fleet Mode”. This operating mode shall indicate a distinct color on the ATS workstation that distinguishes it from other signal modes on the traffic controller’s display. In fleet mode particular signals perform as automatic signals, with the signal returning to its most restrictive aspect automatically, when a train clears the overlap of the signal ahead.

h) In addition to the above, the following functions should also be available and in some cases, the parameters are to be adjustable both automatically and manually: • Automatic Train Regulation (ATR); • Scheduling; • Timetable Editing; • Additional Trains; • Additional Journey; • Cancelation of Trains; • Dwell Times; • Train Describer and Train Identification; • Service and Diagnostic; • Recording; • Traffic Reporting and Statistics; • Simulator; and • Playback.



8.5 Automatic Train Regulation (ATR)

a) The ATR enables trains to be regulated automatically and manually, to achieve a given “traffic quality of service target”. This operates in conjunction with station dwell times and train target speed profile between stations with minimum energy consumption.

b) In order to maintain timetable operation, the ATS shall continuously compare the actual service against the schedule. The system shall provide automatic train regulation in order to minimize traffic deviations from a target “traffic quality of service”. Automatic regulation services shall apply only when the system is set in normal operating mode.

c) The system shall provide services to manage two different “traffic quality of service” targets, these being: • Timetable adherence; and • Headway adherence.

d) Timetable adherence shall minimize deviations between the operating timetable and

actual train movements.

e) Headway adherence shall minimize headway deviation due to train departures at terminal and intermediate stations in order to maintain constant headway as much as possible during perturbations to the system. The system shall not automatically regulate the following types of traffic: • Any non-stop trains; and • Unscheduled trains.

f) Should a changed state occur to the system, the ATR shall also be capable of being

switched into manual mode to allow operator adjustment.

g) In the event of timetable deviation, the ATR shall be capable of immediately implementing a recovery strategy, which shall attempt to restore trains to normal timetable running. The Contractor shall describe their operational philosophies on how they intend to comply with this requirement.

h) Additionally, the system shall provide recovery from the following, which may introduce perturbations into the service: • Disruptions resulting from platform overcrowding and consequentially, extended

dwell times; • Disabled vehicles; • Signaling failures; and • Power failures.

i) Strategy management shall include, but not be limited to the following:

• Centralized automatic regulation;



• Centralized manual intervention; and • Schedule reformatting which may include the addition or deletion of trains.

8.6 Scheduling

a) The scheduling function shall be capable of accepting timetables for regular and specials services (e.g. holidays, weekends, etc.). These timetables may be validated by the use of simulators and are able to be loaded directly into the system. The service will then operate to that timetable. The schedule is required to be loaded in order that automatic regulation operates, otherwise nominal, or default or operator adjusted dwell times will be used. The timetable model shall support the following operating features of the complete LRT Line 2 network: • Operational requirements inclusive of number trains necessary; and • Systematic withdrawal of trains from revenue service.

b) The scheduling function shall support timetables containing as many journeys as needed

to operate a service with a theoretical ninety (90) second headways. The total number of journeys will be calculated based on the operating headway and the number of trains running on the line. An on-line display of scheduled trains shall allow timetable performance to be monitored. Each train scheduled shall display their on-time data measured against the timetable and following information: • Train running number and destination code; • Train location (track section number); and • On-time performance such as:

very early (insert parameters); early; on-time; late; and very late.

c) The time criteria for the above categories shall be the same as presently used. Deviation

from the timetable or failure to leave a platform in a pre-determined period shall generate a warning to the traffic operator.

8.7 Timetable Editing

a) The Time Table Editing shall provide convenient functions and HMI to support off-line

editing of a timetable (creation, modification, and storage.). This function shall permit definition of dwell times and running times for various time periods. The Contractor shall submit the type of timetable editor to be employed for approval and shall provide training for operational staff in the use of such an editor. The timetable editor shall be capable of input of different dwell times per timetable selectable by platform / journey number and by time of day (begin and end times), for establishment of default for each time period of the day. The timetable shall also allow definition of different time periods. Additionally, it shall be possible to manually define a dwell time for any train at any platform during any journey. The dwell times shall be determined by operational requirements.



b) Additionally, different run time performance levels for each journey and by time of day, dependent upon operational requirements shall also be capable of being input to the editor. Definition of any skip station stops by definition of zero (0) dwell time (exception to minimum dwell time) on a station-by-station basis during each journey. Skip stop operations shall only be used when operationally necessary and are not normally scheduled. Therefore, no allowance in any timetables is required for this feature.

c) The system shall provide processing and storage medium for the timetable editor, which is separate from the resources managing the system operation functions. The Contractor shall state the number of timetables that the system allows to be stored within the ATS system.

d) This function shall also provide convenient functions and HMI together with appropriate functional checking to support alterations to the current timetable by the operations supervisor during revenue service should it be necessary. The function shall reject any alteration that would lead to an inconsistent timetable.

e) Time table shall be printable on the existing system and can be exported using excel,

word or other readable format.

8.8 Additional Trains

The Time Table editing function shall allow the insertion of an additional train into the working timetable. The function shall add the new train to the timetable and shall recalculate automatically the departure times of the other trains, so as to achieve equal train spacing provided that the minimum specified headway is maintained. The traffic operator shall specify the running number and the journey of the previous train in the timetable, if the new train is replacing a defective unit, the number of journeys to be run by the new train, the origin of the new train and the final destination of the new train. Trains may also be inserted into the system at any time for operational requirements.

8.9 Additional Journey

The traffic operator shall be able to perform this control to add journeys at the end of service in the loaded timetable. The journeys shall be added to the timetable and the departure times of the trains shall be recalculated in order to avoid shifting of the timetable. The traffic operator shall specify the running number of the train, and the number of journeys to be added for the train, and the final destination of the train.

8.10 Cancellation of Trains

The traffic operator shall be capable of canceling a train from the loaded timetable. The remaining trains and their departure times shall be recalculated in order to avoid congestion of the system. The traffic operator shall specify the running number of the train to be cancelled, the journey number from which the train is to be cancelled (including the journey), and the final destination of the train.



8.11 Dwell Times

a) The dwell time is the amount of time a train stops at a station before proceeding. The dwell time may be adjusted manually, but when used in combination with ATR the value will be attuned upwards or downwards dependent upon whether the train is early or late. The default dwell time shall be set at 30 seconds.

b) When a scheduled train stops in a station, the system shall automatically compute the dwell time at that particular station and a target arrival time in the next station. Calculation of both times shall take into account:

• Current “Regulation Strategy” (Mode of operation); • Current “Target” (schedule or headway); and • Train deviation as compared to the target.

c) The system shall guarantee in any case a minimum dwell time.

8.12 Train Describer and Train Identification (I.D)

a) This function enables the allocation of a journey number to each train on the line and scheduled in the timetable. Each train within the system is given a running number; this unique number allows the train to be tracked. The train describer function enables the operators to view the train as it passes throughout the network. The ATS will identify any train delayed in accordance with the timetable when the train is departing from a station or should the operator wish to display the particular train’s on-time performance record.

b) A train I.D. may be entered manually, if a train is required to be inserted into the system. The running number should automatically change for the return journey. The system shall allow the operator to allocate a train number to a train that has an “unidentified or spurious train number”, or to override a train number.

c) This function shall be capable of identifying all trains in the same sequence pattern as in the timetable or individually by the operator if required to do so. This function shall unambiguously indicate to the operator, which train has been identified. In the event that the system does not associate a train number with the timetable, an alarm shall be produced.

d) The train describer shall indicate all train numbers as they traverse each track section throughout the network. Should the train number fail to step through into the track section upon occupation of the track section or the train number disappears an alarm shall be raised on the operator’s workstation. Train describer berths shall be installed on the mimic panel for each track section, and shall be capable of storing up to several train numbers if necessary.

8.13 Service and Diagnostics

a) The Service Computers are located at the OCC and serve as a user interface for displaying and processing the detected failure stamped with date, time and failure location. It also includes repair instructions for each fault type selected.



b) For the LRT Line 2 East Extension Project, additional Service Computers (with updated software version) shall be made available with similar functions as the existing system. The Service & Diagnostic computer, which is located at OCC, is always connected to the Microprocessor based interlocking system to enable failure messages to be continuously collected. The detected failures are stored in a data-base and report in return to the Service computers. Recording, Traffic Reporting and Statistics.

8.14 Recording

a) The ATS system shall provide several services defined hereunder, which allow users to retrieve information relating to traffic, operator controls and system activities during and after train operation. This data shall encompass events and alarms associated with train movement, signaling system changes as provided by the Microprocessor based interlocking system and wayside equipment. The Contractor shall provide appropriate recording facilities to complement these services. All data generated by the ATS shall be capable of being stored on a suitable medium. This shall allow playback in the event of an incident and also provides information on performance. Back up of the system may be done both automatically and manually. The system shall provide three kinds of recording media:

• Access of the data relating to signaling system wherein operational service is

recorded and available for playback;

• Permanent and removable electronic storage medium, which shall be in the form of a Compact Disk (CD) or USB mass storage devices; and

• Paper recording shall be on a dedicated operation printer suitable for an office environment. Permanent electronic storage medium shall utilize an industrial strength hard drive, compact disk or suitably sized USB mass storage devices.

b) Whichever medium is used, data shall be recorded with the date/time stamp, which shall

be derived from the Master Clock. Recording on electronic medium shall be in ASCII format. Recording on electronic medium shall be on specific data log files each covering one full day from 00.00 to 24:00, incorporating the date as the file name.

c) For the permanent electronic storage medium, the system shall automatically manage opening and closing of daily log files, without any loss of data. Retrieval of the data shall be done using the appropriate file names in accordance with the date of recorded event. The system shall provide the capability to switch data recording on and off through an appropriate HMI. However, if the data recording is switched off, a reminder device shall indicate that currently, events are not being recorded.

8.15 Traffic Reporting and Statistics

a) The ATS system shall be capable of supporting the following reports and statistics for

service analysis. The Contractor shall include an appropriate HMI to display and print: • Theoretical number of roundtrips (based on timetable) on any given day; • Actual number of roundtrips made on any given day;

b) This function shall allow real-time retrieval and display of the above information during operation with automatic refresh of the appropriate page display. Deferred time retrieval after operation shall also be available.

c) This function shall be capable of providing both state-of-the-art graphical and textual display.

d) This function shall allow identification of individual trains and their performance, and can provide printouts.

e) The timetable deviations shall be shown in time-distance diagrams. These diagrams shall portray the route on the horizontal axis and the time on the vertical axis. The time-distance curves shall be distinct by displaying them in different colors. The diagrams shall be able to be printed on a color printer.

8.16 Simulator

a) The use of a stand-alone ATS simulator facilitates the ability to verify software changes before they are loaded into the main system. The simulator shall operate on exactly the same software as the main system and therefore, shall be required to be modified in connection with the requirements of the LRT Line 2 Extension Project.

b) The simulator provides the capability to test timetables and is also beneficial in the training of operators. The ability to print the screen display shall be provided.

c) Subsequent maintenance measures and procedures will be introduced to ensure that storage devices are backed-up on a regular basis. Accessibility shall only be available to appropriate staff with log-in passwords to ensure that only trained personnel are able to gain access to the simulator system.

8.17 Playback

The data generated by the ATS equipment shall be capable of being “played-back” and shall be used in the event of incident or accident investigation. It also allows operations personnel to study information on “quality-of-service” performance. The playback feature shall be selectable by date and time.

9.0 Signaling Hardware and Software 9.1 Interlocking

a) To accommodate the introduction of additional control and monitoring functions associated with the LRT Line 2 Extension Project, the Microprocessor-based interlocking system will be installed at Masinag station. A Microprocessor-based interlocking system at Santolan shall be required to be modified, if necessary.

This network shall adopt fiber-optic cables. The Contractor shall identify and justify their selection of the data transmission system and the associated cabling architecture, which shall include redundancy for high availability. The redundancy configuration shall be similar with the existing LRT Line 2 system.

9.2 Signaling Interlocking System Principles

a) The micro-based signaling Microprocessor-based interlocking system shall ensure that a route to be established for the passage of a train may only set under the following conditions:



• The track section ahead to the next signal and its subsequent overlap is clear of vehicles.

• All point machines within the route are in the correct position, detected and locked. • No conflicting routes are set and the route is free from opposing locking. • Flank Protection is set. • Signal ahead is proved to be illuminated.

b) Prior to the commencement of design work related to routes and their pre-condition for setting, the Contractor shall produce and submit for approval by the Engineer, documents, which shall describe all possible routes and their management based upon operating and Microprocessor-based interlocking system principles as prescribed by the Employer and as indicated in this specification. The documents shall in principle adhere to rules currently adopted for the current Microprocessor-based interlocking system logic. The documents to be submitted by the Contractor shall contain, but not be limited to the following: • A schematic plan of the track layout indicating track sections, signals, points, balises,

cable loops and any other wayside equipment proposed for the project by the Contractor inclusive of their geographical position.

• Interlocking tables (control tables) that depict all routes and the conditions under which they may operate. This shall include entrance and exit point of the route, the track sections, which are required to be clear, overlap, flank protection, points, and opposing routes and locking. Each route shall be individually detailed and any special conditions or controls which may apply shall be listed. Routes that emanate from controlled signals shall be capable of setting automatically in conjunction with timetable and train describer functions as used within the ATS system.

• The Microprocessor-based interlocking system tables shall also include information that describes available speed profiles transmitted by the ATP equipment dependent on data received from the Microprocessor-based interlocking. Where possible, the information shall be prepared on a per route basis.

• All information transmitted between the Microprocessor-based interlocking system and the ATP system shall be included in an appropriate interface document.

• The Microprocessor-based interlocking system tables shall also indicate conditions

for the locking of points. This shall include deadlocking with track sections, route, and overlap locking. It should list which routes request the points to a required position.

• All information transmitted to and from the Microprocessor-based interlocking system and the ATS system shall be included in an appropriate interface document.

• Other documentation relating to functionality and interfaces with the Microprocessor-based interlocking, which the Contractor deems adequate to further describe and explain its operation to the Engineer’s approval.



c) The design of the signaling logic for the Microprocessor-based interlocking system shall be consistent with Microprocessor-based interlocking system principles established for the present Line 2 signaling system. Upon request, the Employer shall provide access to the Contractor to drawings and system currently in use. The Contractor shall also stipulate any additional principles, which may be necessary subject to the Engineer’s approval. The additional control computer to be installed for the LRT Line 2 Extension Project shall comply with the present Microprocessor-based interlocking system principles. This shall include all cross boundary data interfacing with the control computer. The Microprocessor-based interlocking system shall be capable of providing and receiving all necessary data required for the monitoring and control of the system by the ATS system.

d) The electronic Microprocessor-based interlocking system shall interface with the ATP system in order to provide information for maximum allowable speeds with respect to safe braking distances between trains traveling in the same direction on the same line and where trains cross at junctions.

e) ATP target speed profiles to be transmitted to the train shall be provided in conjunction with track conditions ahead. The Microprocessor-based interlocking system shall ensure that only the correct speed profiles are able to be transmitted by interfacing with the ATP equipment. The Contractor shall design Microprocessor-based interlocking system programs and circuitry using fail-safe principles and techniques. All designs shall be submitted to the Engineer.

f) The basis of programs or other software applications shall be consistent with nomenclatures, names, and abbreviations currently used, which shall also be made available to the Contractor upon request.

g) The re-start of Microprocessor-based interlocking system upon restoration of power after

an interruption shall be consistent with the existing system in LRT Line 2.

h) The design shall ensure that any intermittent operation of the vehicle detection system (track sections) from whatever cause shall not initiate premature release of Microprocessor-based interlocking system or any other unsafe condition. Release of the route by the passage of a train shall be achieved by sequential occupation of track sections. The release shall include an inherent time delay; this is to ensure that the Microprocessor-based interlocking system does not prematurely release the route due to a transient operation of the track section.

i) The electronic Microprocessor-based interlocking system shall provide the capability for

manual operation of point machines from both the OCC and the LOW. The request for manual operation of the point machines shall be verified by the Microprocessor-based interlocking system before being executed.

j) Points operated automatically by the Microprocessor-based interlocking system shall remain in their last position until required to be operated by a new route being set or for providing flank protection or manually moved by the operator. The exception is where automatic route setting shall be applied at terminal stations to reduce turnaround times and maintain headway. The Microprocessor-based interlocking system shall monitor all point operations by the use of a timer. If detection is not achieved within a preset time,



the power to the point machine shall be removed. The Microprocessor-based interlocking system shall prevent movement of point machines when the respective track section indicates occupied status. However, should occupancy of a track section containing a point switch occur after the point switch has started moving the movement shall not be stopped.

k) Operation of points shall be interlocked under the following conditions: • Route set through the respective points; • Overlap condition extending through the points; and • Flank protection for route.

l) Points shall be capable of being blocked against any operation from both the OCC and the local workstation. Unblocking of the points must be performed from the same location and shall be registered.

m) The present signaling principles allow points to be moved under track section failure conditions in which the respective track section locks the points. This movement is undertaken with the use of an override command, which also operates a counter that increments each time the override is operated. The override command shall also be logged.

n) The Microprocessor-based interlocking system shall test for the availability of a route

prior to issuing the command to set the route. The initialization command for a route request shall emanate from the ATS system. Should the route not be available for whatever reason, an alarm shall be generated after a pre-determined time or after a number of consecutive attempts to set the route failed. If the route is available to be set, the Microprocessor-based interlocking system shall test to ensure that all conditions such as, track sections within the route and its associated overlap are clear, points are locked and detected, no conflicting routes are set, and any opposing locking is free. Should any one of the conditions not be validated, the route shall not be able to display a proceed aspect at the entrance signal, and no ATP target speed transmitted to the train.

o) The Microprocessor-based interlocking system in conjunction with the ATS system shall be capable of performing ARS. The ARS shall only operate for trains that are scheduled within the time-table or have a valid destination code, and may only function if the following Microprocessor-based interlocking system conditions are fulfilled:

• No conflicting route set; • No other train attempting to use ARS using the same route conditions; • ARS is switched on; and • No opposing route set.

p) The ARS shall attempt to set the route for a number of pre-determined time or a number of consecutive times if the route is not immediately available. Upon expiry of the pre-determined time or number of attempts to set the route an alarm shall be generated by the ATS stating that the route is unable to be set.



q) The setting of a main route enables data to be transmitted to the ATP system. The Microprocessor-based interlocking system shall guarantee that the signal displays a “proceed” signal prior to any information being sent to the ATP system. Routes set ahead of trains enabling them to proceed shall be automatically released by the Microprocessor-based interlocking system upon successful passage of the train.

r) The routes shall be released sequentially providing correct validation of track sections being occupied and cleared in the correct order. Routes set shall remain locked once the train has entered the route. Cancellation by the train dispatcher shall remove all ATP information; the route however, shall not immediately reset and shall only clear after a pre-determined time period has expired. Automatic release of the route shall be performed in the following manner: • Approach track section(s) – occupied; • First track section of the route – occupied; • Approach track section(s) – clear; • Second track section of the route – occupied; and • First track section of the route – clear.

s) Upon completion of the above sequence sectional route release is applied. Route locking

is still applied to the remainder of the route ahead of the train and shall be released upon sequential occupation and clearance of track sections. This sequential releasing of the route behind the train shall continue until the route is completely released. Any interruption of power supply during this process shall cause the automatic route release to cease, and the route locking ahead of the train maintained.

t) The system shall provide automatic routes in all sections of the system. ARS in conjunction with the ATS system shall also be provided.

u) Enables scheduled trains to be automatically routed in accordance with the timetable. The

ARS shall also be capable of being “switched off” should dispatchers wish to reform the schedule due to perturbations.

v) Where routes occupy the same sections of track in opposite directions or where they may conflict, route locking shall prevent any opposite or conflicting route being able to be set. Route locking shall be released upon the passage of a train or by manual cancellation if the route was not used.

w) The Contractor shall provide the ability to block routes for traffic, inspection and maintenance purposes. Blocking or disabling of routes shall be performed at the ATS level. The blocking function shall be supported by a symbolic reference on the monitors on both the OCC and LCW.

x) If an operator attempts to set the particular route that is blocked, a warning prompt shall remind the operator of the route status. Should the operator attempt to re-establish the blocked route, the operator shall be prompted to confirm their action. Blocking of routes shall be implemented between any entrance signal and their respective exit signal. The blocking of a route shall also inhibit the ARS feature. The inhibiting of any route shall be



logged on the event printer for record purposes. Additionally, when the route is unblocked it shall also be recorded in hard copy on the event printer

y) For the LCW, the operational area shall be interfaced with the present system. The Contractor shall adopt the same the methodology as currently used for the transfer from central to local control which controls will remain in the same state prior to any switchover. All indications necessary for operational requirements shall be displayed in a geographical representation of the layout and shall include vehicle detection, point indications, routes set, and signal information. Other indications shall be displayed either by the use of graphics or alphanumerical form. As a general guideline all commands and indications shall be operationally similar to those already used in the existing system.

z) All LCW’s shall be password protected and the user must log-on to the system using an assigned password. Only trained operators with the assigned authorization shall be allowed to gain access to operate the workstation. The workstation shall be located in the room as indicated in the drawings subject to approval of the Engineer.

9.1 Overview

The originally installed SDH / FOTS served as the Telecommunication medium (backbone) for the transmission and reception of Voice, Data and Video information between all eleven (11) existing stations, 6 RSS and OCC of the Line 2 System.

This backbone was based on Synchronous Digital Hierarchy, STM-1 and Plesiochronous Digital Hierarchy (PDH) systems. The fibers installed conform to ITU-T recommendations G.652 wherein the fiber is optimized for networks where transmission occurs across a broad range of wavelengths from 1285 nm to 1625 nm.

After more than 11 years in operation, the current SDH System has become faulty, causing

outages of the various systems passing through it.

Under the Stimulus Fund Project, a new transmission backbone designed to handle simultaneous large amounts of data and video information has taken the function of the SDH system. The new technology called Multi-Protocol Labelling System or MSTP combined with SDH over FOTS comprised a Multi-Service Platform which was recently implemented for the various telecommunication systems of Line 2. Thirty Six (36) core Single Mode Optical Fiber in dual ring configuration interconnected all MSTP equipment in all 11 stations.
