Annual assessment of Network Rail

Each year we publish our assessment of Network Rail’s performance in operating, maintaining, renewing and developing the mainline rail network.

It covers the period from April to the following March.

It expands on other publications issued by ORR, including the quarterly Network Rail monitor, and draws on the Railway Safety Statistical Report.

It relies on the accuracy of data provided by Network Rail in its annual returns.

The independent reporter, Halcrow, audits this data to provide us with confidence in its accuracy.
