Following the two storms this week the majority of the Trans Pennine Express network has substantial delays and cancellations due to the damage caused.
This is expected to take several days to repair due to the extent of the damage.
Check locally, but there is currently a general ticket easement in place across their network. That is to say tickets are available on the services of any other relevant train company, and you can travel on any service (as close as possible to your scheduled time) for Advance Fare tickets.
