Transport for the North has set a "public target" for TransPennine Express to improve its performance.
The move has been agreed by leaders from across the North after the rail operator returned the "worst performance figures in the country" at the end of last year.
Transport for the North have said that less than half of TransPennine's services met basic performance targets and that they now expect them to deliver a service that "restores passenger trust".
The following targets have been set:
- Return performance to early 2019 levels by March 2020
- Improve further on this target by summer 2020
- Show clear progress in restoring its full timetable
- Show clear progress in timely local communication to passengers
Strategic Rail Director for Transport for the North, David Hoggarth, said: "Passengers in the North of England must have a rail service they can rely on.
"In the run-up to Christmas last year TPE simply failed to provide what was needed. The operator must now build back trust and deliver what is needed.
"The new trains are welcome, and the extra capacity they bring is much needed, but service levels must be maintained as they come on stream."
