London Midland disruption: 43 services affected
Forty-three London Midland services have been cancelled or disrupted because of a shortage of drivers.
Trains on the Coventry-Nuneaton, Wolverhampton-Walsall, Birmingham-London Euston, Birmingham-Liverpool and Lichfield-Redditch have been affected.
London Midland said eight shifts were affected, which meant 43 of its 1,300 trains were subject to alteration.
The operator said buses will be provided to replace the 34 cancelled trains.
London Midland has apologised for the timetable changes.
New trainee drivers will be qualified by mid-December, the train operator has said.
