Rail strikes Yorkshire: Everything you need to know about Yorkshire's train timetables during strike week
The railway workers’ trade union, RMT, is planning strikes for Tuesday 21, Thursday 23 and Saturday 25 June.
This will see rail services across Yorkshire - and the rest of the country - significantly reduced, and in many cases, cancelled altogether.
A number of stations across the region will be closed entirely, and no rail replacement buses will be running.
Rail operators around the region have advised customers to avoid travelling on the network between Tuesday June 21 and Sunday June 26.
Where rail travel is unavoidable, operators have warned that journeys will be significantly disrupted and passengers should allow extra time to get to their destination.
While the industrial action only covers three days of the period, services on the days on each side of the strikes are also expected to be impacted.
Below is everything we know so far about how the strikes will affect train travel in Yorkshire.
The rail companies not listed below have not specified which services will be cancelled or running - but have advised customers to avoid travelling by rail altogether on these dates.
Passengers can also check whether their journeys are viable using the National Rail Enquiries real-time Journey Planner. Please note that the journey planner will not be updated with Saturday's (June 25) amended timetable until Wednesday (June 22).
Northern is advising customers not to travel on its network between Tuesday June 21 and Sunday June 26 due to strikes.
