West Midlands rail services face weather disruption
Train operator London Midland has said the stormy weather has caused disruption to its services.
The Cross City route through Birmingham between Redditch and Lichfield was reduced from early afternoon.
Services from London to the West Midlands were subject to a 50mph speed limit for 12 hours from 19:00 GMT.
London Midland lifted ticket restrictions to allow passengers to travel on any of the company's trains.
Commercial director Richard Brooks said extra staff were working to help passengers but said the weather would make travel on Monday afternoon very difficult.
Network Rail spokesman Ben Herbert, said: "All services south of Birmingham will have a speed limit of 50mph from 19:00 GMT for 12 hours as a precaution as storms are expected to worsen this evening".
He said the restricted speed was "likely to lead to further delays" for south-bound journeys from Birmingham New Street.
The Met Office issued amber warnings for rain in Wales, the east of England, south-west England and London and south-east England on Monday.
The Environment Agency issued more than 30 flood alerts across the West Midlands.
