When thousands of workers walk out across the UK on June 21, 23, and 25, Network Rail estimates that half of all rail lines will be closed.
The services will begin and end earlier, from 7.30am to 6.30pm
There will be no trains in many places, including Glasgow and Edinburgh, as well as Penzance in Cornwall.
Network Rail, which owns and operates the country’s railways, also announced that passenger services to Bournemouth in Dorset, Swansea in south Wales, Holyhead in north Wales, Chester in Cheshire, and Blackpool in Lancashire would be suspended.
The West Coast Main Line, which connects London to Scotland via Birmingham and Manchester, is one of the open lines.
Due to the fact that trains run for fewer hours on strike days, final departures will be much earlier than usual. For example, the last train from Manchester to London will depart at 14:47, the last train from Norwich to London will depart at 4pm, and the last train from London to Edinburgh will depart at 3pm.
The action will have the greatest impact on rural and district lines.
The timetable from 20 to 26 June is still being finalised, but Network Rail estimates that the number of services will be around 4,500, compared to 20,000 normally.
Disruption is also expected to extend into non-strike days during the week, with only about 60% of services expected to operate.
