Some services have started running out of Paddington station today (September 20 ) today but travellers from the West are being warned to expect delays.

Trains were suspended after trains became entangled in overhead power cables.

Four tracks reopened at 09:30 BST after engineers worked overnight but disruption is expected to continue until lunchtime, Network Rail said.

Services will also finish before 22:00 to allow further work on the lines.

While all four tracks are now open, overhead electric wires are only in operation on two of the lines.

No trains had been able to run from Paddington station to West Drayton and Heathrow Airport, although from early on Tuesday morning there was a shuttle service to Ealing Broadway every 30 minutes.

National Rail has advised:

• Passengers travelling between London and Reading should travel to/from London Waterloo using South Western Railway services
