Commuters may encounter severe delays on London Underground lines this morning (28 January) with the Elizabeth line part suspended due to a power supply problem.
There is no service on the line between Paddington, Reading and Heathrow Airport with severe delays on the rest of the line due to a power supply problem at Paddington.
All Great Western Railway routes to and from London Paddington, as well as the Heathrow Express between London Paddington and Heathrow Terminal 5, have also been disrupted.
National Rail said: “A fault of the electricity supply between London Paddington and Heathrow Airport / Reading means some lines are blocked.
“Trains running between these stations may be cancelled, revised or delayed by up to 60 minutes.”
According to the rail operator, major disruption is expected until 2pm with engineers working to “establish the cause of the failure and what areas are affected”.
London Underground and London Buses are accepting tickets via reasonable routes, said TfL.
Elsewhere, a track fault at Wembley Park has caused severe delays on the Metropolitan line.
Commuters can use tickets on the Lioness line, London Buses and Chiltern Railways.
Those planning to use the Jubilee line will also find minor delays between North Greenwich and Stratford due to an earlier signalling problem.
