Punctuality by region

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.

The table below includes the following four regions:

Birmingham line - all trains serving Princes Risborough or any station north thereof

High Wycombe line - trains only serving stations Princes Risborough, Aylesbury (or south thereof, via High Wycombe)

Aylesbury line - all trains serving Aylesbury Vale Parkway or any stations south thereof (via Amersham)

Oxford line - all trains serving Bicester Village or any station north thereof
