Passengers have been warned of widespread disruption on the railways caused by industrial action by staff on Saturday.
Only four trains will run from Bridlington and Scarborough and only 10 will set off during the day for Hull, as Northern Rail estimates that two-thirds of its services will be cancelled across the north of England.

Services to Scarborough will only be running at 9am, 12.06pm, 3.35pm and 8.16pm.
The final train back to Bridlington from Hull will be the 7.22pm, and the last one from Scarborough leaves at 4.25pm.
Northern Rail said very few trains will be running anywhere after 5pm.
On its website, the company said: “We will provide a limited number of train services. The services we will provide are based on the availability and location of Northern employees who are trained conductors.
“Wherever possible, we are also focussing services on our busiest routes into major towns and cities.”
Sunday’s timetables should not be affected and TransPennine Express which runs trains from Scarborough and Hull to Manchester and Leeds is not affected.
