https://www.bbc.co.uk/news/uk-england-manchester-64062834?at_medium=RSS&at_campaign=KARANGATransPennine Express (TPE) has had to cancel dozens of services for a second day running with some linked to an ongoing IT problem.
The operator said a software issue that caused [size=inherit]
more than 100 cancellations on Wednesday[/size] had not yet been resolved.
TPE said it was working "flat out" to solve the problem, and knock-on delays.
Greater Manchester Mayor Andy Burnham has criticised TPE's performance and said the government should step in and put the firm "on immediate probation".
TPE, Avanti West Coast (AWC) and Northern have all had problems with cancellations and delays across the north of England and parts of Scotland in recent months.
The three operators [size=inherit]
introduced new timetables[/size] earlier in December, which were aimed at solving some of the problems.
TPE said the latest disruption was caused by a software issue "rather than a staffing problem", which led to it advising passengers not to travel on Wednesday.
The operator said the issue was affecting rostering and could cause further disruption over the coming days.
[size=2rem]'Unprecedented pressure'
Mr Burnham told [size=inherit]
BBC North West Tonight[/size] the government should "step in" and put the operator on "immediate probation", as it had done with AWC.
That operator has been given until 1 April [size=inherit]
to improve its performance[/size] following a summer of problems.
The Labour mayor added that if TPE's services were not "better by the early part of January, they should be out".
