Northern Rail passengers have been issued advice for travelling during the strike-affected festive period.
The National Union of Rail, Maritime and Transport Workers (RMT) announced additional strike dates over Christmas after rejecting a pay offer from Network Rail. Workers will now go on strike from 6pm on December 24 until 7am on December 27, as well as going ahead with planned walkouts on December 13 to 14 and 16 to 17.
As a result of industrial action from the RMT, Northern Rail has advised customers not to travel on its network between December 13 and 17 due to "major disruption across the whole rail network ". Additionally, passengers planning to use the network on the newly-announced strike days have been told to travel by rail only if necessary.
