Rail union the RMT will hold six days of strikes on consecutive Saturdays – 25 August, 1 September, 8 September, 15 September, 22 September and 29 September – which will impact on rail services in the region.
On Saturday 25 August - the first day of RMT strike action - the company say they will operate almost 30 per cent of their services, with very few running before 9am and after 6pm.
All customers are advised to check before travelling and, where necessary, may want to seek alternative modes of transport.
The long-running dispute concerns plans to remove conductors from most Northern rail train services, moving to so called driver-only operation (DOO).
