Rail commuters in the north of England have been hit by cancellations and delays as new winter timetables were launched.
Northern had cancelled 19 trains by 10:00 GMT and 31 were delayed, which it said was down to "operational issues" rather than the timetable change.
Transpennine Express also cancelled 29 services on Monday morning.
The issues largely affected commuters in Yorkshire, Greater Manchester, Lancashire and Merseyside.
Transpennine Express services hit included those linking Manchester Airport with Edinburgh and Newcastle, and trains from Liverpool Lime Street to Scarborough.
The firm's managing director Leo Goodwin said he was "really sorry" for the disruption to customers at such a busy time of year.
He said: "Due to a number of issues with crew training caused by the late delivery of some of our new trains, along with a maintenance backlog and some infrastructure issues we have had to implement a temporary timetable, cancelling some journeys along one of our routes."
Northern services which were affected were between Blackpool North and Manchester Airport, from Leeds to York and Sheffield, and Darlington to Saltburn.
A spokesperson for the rail firm said: "Very few of our services have seen any changes as a result of the timetable coming in.
"The small number of delays and cancellations are due to operational issues including driver sickness, signalling failure and train faults."

Transpennine is running a pre-planned temporary reduced timetable on some routes as a maintenance backlog and infrastructure problems have delayed staff training on new trains.
Its managing director Mr Goodwin said as new trains were introduced improvements to services would be made.
