More than 30 London Midland train routes are cancelled today because of a shortage of drivers.
The company says temporary cancellations and changes to services will be taking place until the middle of December due to a lack of qualified drivers.
They say several services would be affected on Tuesday.
These include trains between Coventry, London Euston, Northampton, Birmingham International and Birmingham New Street as well as between Redditch, Lichfield and Four Oaks.
London Midland say they will be providing daily cancellation updates between 22 October and 11 December at 17.00 for the next day and the day after that.
