Question to the Department for Transport:

To ask the Secretary of State for Transport, what proportion of trains on the Southeastern rail network have been delayed in the last 12 months; and what proportion of those delayed trains were the fault of (a) Southeastern and (b) Network Rail.

Statistics on passenger rail performance are published by the Office of Rail and Road (ORR).

The current standard measure of train punctuality is the Public Performance Measure (PPM). PPM is defined as the percentage of trains arriving at the final destination within five minutes of the planned timetable for London and South East, Regional and Scotland operators, or within ten minutes for the Long Distance operators.

Published PPM statistics per train operator up to Rail Period 11 2018-19 (January 2019) are available on the ORR website at the below link:

The latest available statistics show that in the year ending Period 11 2018-19, 88.1% of planned Southeastern services arrived at their final destination within five minutes of the planned timetable.

Statistics on train delay by cause are currently available up to Period 7 2018-19 (October 2018) and are also published by the ORR at the below link:

In the year ending Period 7 2018-19 (October 2018), 87.7% of planned Southeastern services arrived at their final destination within five minutes of the planned timetable. Over this year, 61% of Southeastern PPM failures recorded were attributed to Network Rail, whilst 32% of PPM failures were attributed to Southeastern. The remaining PPM failures occurred as a result of delays attributed to other Train Operators, as well as small proportion of delays for which it is not possible to attribute to a specific cause.
