Richard Allan, deputy managing director of Northern, said: “We are very disappointed that the union has announced strike action for Friday 28 April. More than anything, we are sorry for the disruption it will again cause our customers, but we have robust contingency plans in place to keep our customers on the move where possible.

“Everyone has a big role to plan in shaping our modernisation plans. There is a lot to discuss and we urge RMT to get back round the table with an open mind as soon as possible. In addition to protecting jobs and current pay, we are also willing to offer future, annual pay reviews for existing conductors if we can agree a deal with RMT.”
