Here the PA news agency answers 10 key questions about what happened and what comes next.

– What is TransPennine Express?

A train operator running intercity services across northern England and into Scotland.

Cancellations and delays have been widespread for several months.

The equivalent of nearly one in four trains were axed in the four weeks to March 4.

A series of issues including drivers no longer volunteering to work paid overtime shifts and higher than usual staff sickness levels.

– What has been the reaction?

West Yorkshire mayor Tracy Brabin said it was “absolutely right”.
