Overview
- A signalling fault near Darlington was resolved and all lines reopened, though delays of up to 20 minutes continued into the morning.
- Services on routes between Middlesbrough and Newcastle via Darlington, between York and Newcastle, and to and from Middlesbrough and Saltburn were affected.
- Northern attributed morning cancellations to an unusually high number of trains needing repairs at the same time.
- Evening changes included the 7:27 pm Bishop Auckland–Saltburn service terminating at Middlesbrough and the 8:59 pm Saltburn–Darlington service being cancelled.
- Northern advised passengers to check journey planners and, if their train is cancelled, use Northern, TransPennine Express, East Midlands Railway or LNER within two hours of the scheduled departure.
