For information on how the train service is performing
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.
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).
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.
