A derailed train at London Paddington is causing disruption to trains running to and from the station.
Great Western Railway are warning that trains may be cancelled or delayed by up to 20 minutes.
- Between London Paddington and Bristol Temple Meads
- Great Malvern
This is expected to continue until the end of the day.
It comes as a severely reduced service is currently running with at least 50 percent fewer trains on South West Trains at London Waterloo due to engineering works.
Tickets being accepted on reasonable routes with Southern, Thameslink and Great Western Railway services.
