Chiltern Railways is also warning commuters that trains are likely to be overcrowded as peak-time trains will be both less frequent and shorter than usual.

During the special timetable trains departing from Bicester North and Banbury to Birmingham will not serve Stratford-upon-Avon, Wilmcote, Bearley, Claverdon and passengers will need to change trains at Birmingham Moor station.

The operator has said the same service is set to remain in place for tomorrrow.
