TransPennine Express services will face "widespread disruption" by rail strikes over the next month and will not serve Liverpool on strike days.
The National Union of Rail, Maritime and Transport Workers (RMT) are planning to strike on December 13-14, 16-17, as well as January 3-4 and 6-7. The Transport Salaried Staffs' Association (TSSA) will also take action on December 17.
Workers at the RMT will also walk out from 6pm on December 24 until 6am on December 27 in the latest stage in a long-running row pay and conditions. Earlier this week, the union recommended its members should reject the latest offer from Network Rail (NR), claiming train operating companies still awaited a mandate from the Government.
