Barton services should be unaffected as they are crewed by TPE staff, however other Northern services will be affected. In particular, in our area note that as all three dates are Saturdays there is unlikely to be any Brigg line service and services to Hull will be severely reduced.
There is now additional strike action on Saturdays 15th, 22nd and 29th September.

Fee free refunds are available for anybody who chooses not to travel.
Further RMT industrial action on Northern now planned for Saturdays 6th, 13th and 20th October.
