Rail operator London Midland has promised passengers that the chaos of September 6 when drivers failed to turn-up for work will not happen again.
Company director Mike Haigh was held to task over Sunday working, despite the situation remaining unresolved for more than two years since it took over the franchise.
Mr Haigh pledged assurances to members of the Integrated Transport Authority and added that London Midland, which runs services from London to Birmingham, is in negotiations with trade unions to try and resolve the issues.
Following the mass cancellation of services on September 6 - the operator was criticised by the Department for Transport and ordered to spend millions of pounds improving services for breaking the agreement it signed in 2007.
The company has now reinstated double time working until January 17 but members of the transport authority fear problems could occur in the following week.
Responding to the criticism, Mr Haigh, said: “We will not see a repeat of Sunday, September 6. What I can’t say is whether or not that will involve an extension of the double time agreement. That would prejudice any negotiations but suffice to say we will not see a repeat of the problems on the weekend after January 17.”
London Midland drivers are not required to work Sundays, and the operator had relied on volunteers who signed up for weekend shifts in return for double pay.
But volunteers withdrew after the company cancelled the enhanced pay, leaving trains standing idle.
Despite the inherited problems with contractual agreements, members of the Integrated Transport Authority said negotiations had taken too much time. London Midland conceded progress had been slower than expected.
ITA member Councillor Roger Horton said: “Nearly three years down the line and the situation hasn’t been resolved. In the 21st century a service can’t be delivered by relying on volunteers. I am worried and frustrated.”
Mr Haigh also dashed hopes of campaigners calling for London Midland to provide more services over the Christmas period. He confirmed no trains or replacement bus services will operate during Boxing Day, which falls on a Saturday.
He said: “It isn’t commercially viable give the high fixed costs involved and in terms of the high profile issue of Sunday working - if we were to offer incentives for staff to work Boxing day it could jeopardise the services on the Sunday and Monday. The risk was too high.”
