Purpose The Possession Indicator Report (PIR) presents Network Rail’s performance against the regulatory Network Availability outputs set by the Office of Rail Regulation (ORR) in the final determination for the Period covering 1 April 2014 to 31 March 2019 known as Control Period 5 (CP5). The PIR is published every four weeks and includes a series of other key disruption indicators. Structure of this report The PIR is structured under the headline measures shown in the Table below:
Metric Definition Purpose
1.Possession
Disruption Index
for passengers
Possession Disruption Index for
Passengers measures the
economic value of the impact of
possessions on excess journey
time as experienced by
passengers.
The measure aims to reduce the
disruption experienced by the
customer and is expressed as an
index (PDI values divided by the PDI
at the end of 2007/2008).
2. Possession
Disruption Index
for freight
The Possession Disruption
Index for Freight provides
network availability measures
the ‘availability’ of track for
freight use, weighted by the level
of freight traffic operated over
each section of track.
The measure aims to ensure that
freight services experience no
increase from 2007/8 levels of
disruptions resulting from engineering
works. The measure is expressed as
an indexed normalised by the MAA
for 2007/8.
3. CPPP & EAS
Disputes
The level of access disputes
escalated to the Access
Disputes Committee (ADC)
through the engineering access
planning process, or after the
Confirmed Period Possession
Plan.
This is a leading indicator. This
assess whether the access planning
processes are working as they
should.
4. Weekend
working
timetable
compliance
Working Time Table compliance
measures the percentage of
train schedules that ran as
scheduled or were disrupted
(cancelled or replaced by buses
vs. the permanent timetable)
each weekend by franchised
passenger train service
operators.
The measure provides visibility of the
levels of weekend timetable
compliance with a view to delivering a
90% compliance aspirational target.
5. Rail
replacement bus
hours (weekend)
Rail replacement bus hours
measure the percentage of train
schedules that ran and were
disrupted (cancelled or replaced
by buses vs. the permanent
timetable) per weekend, per
TOC.
The Rail replacement bus hours
measure provides an indication of the
extent of bus substitution at
weekends.

6. Number of
planned
disruption
mitigation
interventions
(SLW, BiDi,
Simbids)
Measures the number of
adjacent line open interventions
planned to minimise the impact
of planned engineering work on
rail users.
The measure includes the number of
possessions planned with either bi-
directional signalling, single line
working or Simplified Bi-Directional
Signalling in operation to enable
trains to run during engineering work /
line blockages.
7a Notification
discount factor -
% Possessions
notified post TW-
22 Timetable
Possession Notification
Discount Factor measures the
percentage of disruptive
passenger possessions notified
in each of the three possession
notification bands.
The measure serves as an incentive
to plan possessions as far in advance
as possible. This helps passengers
plan their journey's better as fewer
changes are made to the published
timetable.
7b Notification
Discount Factor
by spend
Possession Notification
Discount Factor measures the
number of payments and spend
of disruptive passenger
possessions.
The measure serves as an incentive
to plan possessions as far in advance
as possible. This helps passengers
plan their journey's better as fewer
changes are made to the published
timetable.
8. Planned
disruption - Late
notice
possession
changes
Measures the number of new,
cancelled, curtailed or extended
disruptive possessions that were
agreed between the CPPP and
the WON as approved by the
Engineering Access Planning
unit (EAP).
It captures Network Rail driven
changes which have an additional
material impact that will be felt by the
travelling public and/or freight
customers (e.g. cancelled trains, re-
timings and diversions away from
stations), compared to what was
published in the Confirmed Period
Possession Plan (CPPP).
9. Delay
minutes due to
possession
overrun
The indicator is the delay
minutes per 100 train kilometre
run due to possession overrun.
The measure aims to provide a view
of the levels of passenger journeys
disruption resulting from extended
journey times due to overrunning
planned engineering works.
10. Cancellation
minutes due to
possession
overrun
The number of equivalent delay
minutes per 100 train kilometre
run caused by cancellations due
to possession overruns
The measure aims to provide a view
of the levels of passenger journeys
disruption resulting from cancelled
train services due to overrunning
planned engineering works.
11. Unplanned
temporary
speed
restrictions
(TSR)
The Unplanned TSRs measure
provides an indication of the
number of unplanned TSR’s in
place.
The measure aims to provide a view
of the disruptions to passenger
journeys resulting from unplanned
TSR.

Caveat The principal measures of the availability of the network to run trains are the Possession Disruption Indices for passenger (PDI-P) and freight (PDI-F). Following franchise changes in 2015, the Network Availability Reporting System (NARS) was unable to report PDI-P figures between April 2015 and February 2016. Throughout CP5 train service codes have been divided amongst service groups and subsequent weightings been re-distributed, adversely affecting the figures produced. PDI-P ended 2016/17 at 1.25 per cent, significantly higher than expected when the original forecasts for CP5 were made. However, service group changes resulting from changes to franchises mean that this out-turn is unreliable, not representative of our performance and not comparable with the regulatory targets that were set by the ORR before the start of the control period. We do not believe that PDI metrics are now a reliable indicator of network availability. Furthermore, PDI measures are not used by our business to inform possession planning decisions and we are further aware that PDI is not a measure that is valued by the industry. Following discussions with the ORR, we will continue to report PDI data until the end of CP5 for regulatory purposes, recognising that there are fundamental weaknesses in the measure. We have introduced two early warning indicators which we will monitor and publicly report (via our Annual Return), these are: i) level of access disputes raised and ii) additional information relating to the notification discount factor. These measures will more accurately monitor and track our ability to effectively plan possessions in line with industry processes and the impact they have on both industry and end users. We believe this will provide assurance to the industry in the absence of reliable PDI data. We consider that it is likely that the PDI-F calculation has similar issues to PDI-P.

The moving annual average for Period 11 was 1.20, again improving when compared to the same period in 2017/18 of 1.47. Period 11 included major works north of Sheffield Major renewals in the Cricklewood area, Track Renewals and Maintenance Purley to Balcombe Tunnel Jn, Track renewal between Purley to Tattenham Corner/Caterham, Re-signalling works Keymer Jn/Falmer to Seaford/Berwick, Orpington Switches & Crossings (S&C) work, maintenance work on the Northampton loop, Kilsby tunnel work and Dorridge Freight loop lengthening. Passenger services were also impacted due to work Millom to Sellafield, Shrewsbury-Crewe, Preston to Blackpool, Kirkham Drainage Clarbeston Road-Milford Haven and Cardiff Central electrification works. East Coast mainline services were diverted via Cambridge due to S&C and Overhead Linework between Sandy and Peterborough, S&C renewal at Peterborough also saw some significant alterations to the train plan, access to Crofton Depot was limited due to rerailing going on between Crofton East Jn and Pontefract West Jn. Passenger service were impacted by rerailing and platform extensions between Haltwhistle and Petteril Bridge Jn. NOTE: Possession Disruption index for Passenger is reported a period in arears.

The moving annual average for Period 12 was 0.97, again improving when compared to the same period in 2017/18 of 1.00. Period 12 saw Freight services impacted by various planned engineering works including the first 12 days of a two 19-day blockades planned concurrently, one between Taunton and Exeter for Whiteball Tunnel Lining repairs, and the other between Totnes and Plymouth for track renewals work in Marley Tunnel. Over the period there was restricted access to Derby RTC, Litchurch Lane works, Wellingborough Up Yard and Elstow sidings. Trains were diverted via Masborough and Barrow Hill with Hope valley services having to reverse at Chesterfield. A major bridge renewal closed the mainline into Immingham with limited traffic being diverted via the Grimsby light railway. S&C renewal at Peterborough affected some freight services that were required to use the March lines which had to retime around the end of the possession. Freight services were also impacted by work Balshaw Lane Jn to Preston, Sydney Bridge Jn to Sandbach South Jn, Preston to Blackpool, Millom to Sellafield, Allerton Jn & Liverpool South Parkway to Hunts Cross, Ardwick to Guide Bridge, Margam to Llanelli for Port Talbot Resignalling preparation work and electrification at Cardiff Central and at Newport. Fenny Compton freight loop lengthening resulted in freight not being able to use the loop and having to divert via West Coast mainline and the Western Route. Throughout the period significant amendments were made to freight services in the Southampton area as part of the Southampton freight upgrade programme. Unfortunately, primarily due to safety related issues, many of these works were not successfully completed during the period and will now need to be undertaken at a later date.
