4.0 Introduction: -

Hot axle box in a railway vehicle occurs when inadequate wheel-bearing lubrication or mechanical flaws (bearing failure) cause an increase in temperature. If undetected, the bearing temperature can continue to rise until there is a bearing “burn-off” which may cause a derailment.

Currently hot boxes are detected on running trains by station staff by listening to the whistling sound of bearings and visually due to discoloration of axle-boxes and grease oozing out. At station or in yards, when the trains stop, hot axle-boxes are detected by physically touching the axle-box cover. Of late, hand held non-contact infrared thermometers are also being used at major stations for checking the temperature of axle-boxes.

Hot Axlebox Hot Wheel Detector system (HAHW system) is a fully automated wayside detection system. It consists of data acquisition equipment deployed by the side of railway track which acquires temperatures of axle boxes and wheels treads / rims. The

To be clarified the Fail‐Safe Requirement. Is there a hazard analysis available to identify which functions should have a safety integrity level?

This comment seems unconnected to this clause. However, this requirement has been clarified later.

acquired data is analyzed and axle boxes running hot due to some defects and wheels running hot due to brake-binding are identified. Alarms are raised when the parameters are found exceeding limits. These alarms are dispatched in the form of SMS alerts or any other suitable means. The parameters acquired by system are also relayed to a computer server which is available to users of the system through a website.

RDSO along with IIT, Kanpur have developed fully automated infrared sensor based wayside detection system that can make measurements of temperature of axle boxes and wheel treads/rims on a train traveling up to 70 Kmph. This specification, although based on this prototype, has been framed such that it is sufficiently broad in nature to permit any potential/existing manufacturers, developers, system integrators and tenderers to supply such equipment to Indian Railways provided they meet the requirements spelled out in this specification.

The purpose of this specification is to spell out the functional and technical requirements of a HAHW system to enable manufacturers, developers, system integrators and tenderers to supply such equipment to Indian Railways on requirement.

Dy.CME(C&W) / ECR:- The equipment should be capable to measure temperature of axle boxes & wheel treads/rims on a train traveling up to 120 KMPH, not 70 KMPH.

Partially accepted. Relevant changes have been made in clause 8.1.9, 8.2.6 and 8.2.7.2.8. Option of speeds 0-70 is also retained so that in case if a high speed HAHW system is considered too costly, then the option of purchasing a low speed HAHW system at lowers cost remains open.

For each train the reports should be checked for following aspects: -

5.8.3.1.1 That the ambient temperature reported by the HAHW equipment

and any other thermometer is ± 1.5 0C 5.8.3.1.2 That the temperature of axle boxes

and wheels are not below ambient for each train.

Some variation is expected depending on the time the train has passed the HAHW and the time the same train is checked in the station/yard. The variation should be consistent. The correlation should be at least 75%.

General Comments:-

Dy.CME(C&W) / ECR:- 1. Utility is doubtful like in case of WILD where only 4

wagons found defective (4 flat wheels found out of 88 alarms generated.)

2. The cost/benefit analysis is a must vis-a-vis non-contact thermometers.

3. No monopoly of supplier should be accepted, product should be launched only after having 3 to 4 venders available.

4. For wayside equipment like weighbridges, WILD, HAHW securing of cables / from rail joints for preventing damages by feet of animals/human should be made.

5. Such equipment shall be independent of track breathing, straightness of track etc. These are practically not possible.

RDSO’s response 1. RDSO has studied the issues related with WILD and the utility

has been established to different degree depending on different modes.

2. Agreed.

3. Agreed. This technology is widely prevalent in different countries as such enough vendors should be available.

4. Agreed. This should be taken care of during installation and commissioning.

5. Such equipment are generally fitted on straight and level track and can accommodate minor imperfections in track.
