Our Performance

We work hard to make sure your journeys with us run smoothly. And we want to be as open and honest as we can when we talk about our performance.

We measure our performance in a number of different ways. For a more detailed breakdown of how our services are doing, download our monthly performance PDF report.

New ways of measuring performance

From 1 April 2019, all train companies will publish ‘On Time’ (to the minute) performance figures. These will show the percentage of station calls that were on time.

These figures, as well as other detailed results, can be found in our monthly on-time PDF report.

Punctuality and performance

Punctuality - the percentage of our trains that arrive at their destination within an agreed ‘on-time’ window
Reliability - the percentage of our trains that run

Customer satisfaction

National Rail Passenger Survey: Autumn 2018
