RAIL passengers are being warned of weekend disruption as RMT train managers launch a series of weekly walkouts this Sunday.

Union members are set to walk out every Sunday until May 25 in a dispute over rest day working at Avanti West Coast.

A reduced timetable will be in place on the strike days, with fewer services running during limited operating hours.

Trains which will run are expected to be busy.

Timetables for each strike date may vary and take longer to be finalised as planned engineering works are taking place on most of these Sundays.

Customers who do travel should plan ahead, expect disruption and check the details of their last train home, said Avanti.

Kathryn O’Brien, executive director of customer experience at Avanti West Coast, said: “We remain open to working with the RMT to resolve the dispute.”

On Sunday, Avanti West Coast will run one train an hour between London Euston and each of Birmingham, Manchester, Liverpool and Preston.
