West Midlands Railway and London Northwestern Railway will only be running a "very basic" service on Saturday as members of the National Union of Rail, Maritime and Transport Workers union take strike action.
Bus replacement services will run on the following routes, it said:
- Walsall - Rugeley
- Wolverhampton - Shrewsbury
- Kidderminster - Worcester
- Shirley - Stratford-upon-Avon
- Bromsgrove - Droitwich Spa - Worcester
And this is the timetable for their planned rail services:
- Cross City: Lichfield - Birmingham - Bromsgrove / Redditch
- Snow Hill Lines: Kidderminster - Birmingham - Whitlocks End / Dorridge
- Wolverhampton - Smethwick - Birmingham - Walsall
- Birmingham - Coventry - Northampton
Virgin Trains, Cross Country, Chiltern Railways and Transport for Wales are due to run a normal Saturday timetable, but will be busier, it added.
