No trains will run between Bridlington and Scarborough next Tuesday and Thursday - as the latest strikes are held on the railways.
A limited service has run on previous occasions when there has been industrial action - but timetables for next week show there will jiust be three replacement bus services between the two towns.
Trains will run between Bridlington and Hull, but there will be even fewer than on previous strike days - with the first service to Hull leaving at just after 7.30am and the final train back to Bridlington at 5.18pm.
RMT members are also planning to strike next Saturday, June 23 - but a revised timetable has not yet been released.
A statement from Northern Rail said: "To help keep you on the move during RMT strike action on Tuesday 19, Thursday 21 and Saturday 23 June we will run as many services as possible each day.
"On Tuesday and Thursday, the majority of available trains will operate between 7am and 7pm as we focus on running as many trains as we can to get you into work and home again.
"On Saturday, most trains will run between 7am and 7pm, though, on a handful of routes, services will begin to wind down earlier.
"As the overall number of trains running will be reduced across the three days, we expect trains and any replacement buses we operate to be extremely busy. Please allow extra time for journeys, plan carefully and consider whether travel is necessary."
