Our performance

We want to be as honest and open as possible when we talk about our performance.

The age of our trains, stations and lines are still a major challenge. But a huge amount of work has been carried out since the start of our franchise, and we believe our customers are now beginning to see some real benefits.

Punctuality and reliability


Punctuality is the number of trains that arrive at their final station on time. The ‘on-time allowance’ is the leeway we have, to still be classed as on time. 


Reliability is the number of scheduled trains that run.

Updated Friday 1 June 2018. Discounts apply from 3 June 2018 to 30 June 2018 inclusive.

Void days

A void day is when there’s a serious disruption at peak time, and we haven’t offered you another way to get to where you are going.

We will put posters up at our stations, and get in touch with you by email or post.

We'll explain what happened, and how you can claim either a season ticket extension or a refund.

Discounts for renewed season tickets

If you are entitled to a discount, we’ll take it off when you buy your new ticket.
