Punctuality = percentage of peak hour trains arriving no later than 5 minutes after scheduled time.

Reliability = percentage of scheduled weekday trains actually run.

We are also measured by the Department for Transport (DfT) on our all day PPM (Public Performance Measure). This measures the punctuality of all our services, 7 days a week

The public performance measure (PPM) shows the percentage of trains which arrive at their terminating station on time.

PPM combines figures for punctuality and reliability into a single performance measure. It is the industry standard measurement of performance.
