Train service punctuality and reliability

For information on how the train service is performing – check below for yesterday’s service

On time punctuality

We publish a measure of train punctuality as part of national plans to improve train service performance, reduce delays and increase transparency with ‘to the minute’ punctuality data. It is known as 'On time' and records punctuality at each station along a journey. We have been reporting data in this format since April 2019.

The current data known as the public performance measure (PPM) considers a train to be on time if it arrives within 5 minutes of its scheduled arrival time (or 10 minutes for long distance operators).

The daily report

Every day we publish our performance statistics for the previous day. We report two figures:

PPM – the percentage of trains arriving at their destination within 5 minutes of schedule
On time – the percentage of trains arriving at the scheduled time at each station stop on a journey

Station by station performance

You can now view periodic (4-weekly) performance data for punctuality and reliability of train services at individual stations. This data includes the percentage of trains arriving at the station within three minutes of their scheduled arrival and the percentage of trains that were scheduled, but did not call at the station.
