Railway passengers in Carlisle face major disruption today, because of strike action.
Workers from the Rail and Maritime Union are holding a 24-hour walkout in a dispute over train operator Arriva Rail North's plans to change the role of train guards.
All Northern services from Carlisle railway station are affected, including trains to and from Newcastle and West Cumbria.
Passengers travelling on the Settle-Carlisle service, and between Oxenholme and Windermere, will also be affected.
Northern says it will run as many services as possible, and will provide replacement buses.
It's the third time RMT members have walked out, to protest against plans for driver-only trains to come into service in 2020.
Arriva Rail North, who operate the Northern service, said the strike action was "disappointing".
