Train passengers have been left stranded in west London after a fault with overhead cables forced all services to stop.
Great Western Railway said disruption was expected on the London Paddington to Reading line until the end of the day.
A Network Rail spokesperson said the overhead cables affected were in the Ladbroke Grove area.
The spokesperson said: “We’ve had to stop all services while our engineers work as fast as they can to fix the issue. Our teams are also working with train operators to assist people on the trains affected.
Aware of a serious incident involving overhead wires outside Paddington, with a number of trains stationary on the tracks. @transportgovuk is working with @networkrail, train operators & @BTP to help passengers, with teams on the scene.
