Passengers will be hit by another rail strike this Saturday - and the disruption will continue every weekend until the New Year.
It is the 12th consecutive Saturday where industrial action has affected timetables on the Yorkshire coast line.
Northern Rail staff who are members of the RMT union last week announced plans for seven more weeks of disruption in a long-running dispute over the roles of guards.
This week's timetable on the Scarborough to Hull line is:
Bridlington to Scarborough
No trains running, replacement buses will leave at 7.33am, 1.15pm and 6.08pm.
Scarborough to Bridlington
No trains running, replacement buses will leave at 6.15am, 11.46am and 3.15pm.
Bridlington to Hull

Hull to Bridlington
Trains leave at 9.30am, 12.30pm, 2.30pm and 5.15pm.
