Engineering work is taking place between Rugby and Milton Keynes, closing some lines.
From Monday 4 May to Sunday 17 May, all Avanti West Coast services will be diverted to run on an alternative route between Rugby and Milton Keynes Central. This will result in journey times being extended by approximately 15 minutes.
Trains will arrive at London Euston slightly later than usual and leave London Euston slightly earlier than usual.
