all passengers have been warned of serious disruptions after train services on Paddington Station were suspended.
Great Western Railway (GWR) said all lines between the west London station and slough, Berkshireare blocked due to damage to overhead power lines.
The issue has also caused delays to trains traveling from Reading and Heathrow Airport.
Services from GWR, Heathrow Express and the Elizabeth line were affected, with disruptions now expected through the end of the day.
Passengers with tickets for canceled or delayed services can use them on South Western Railway, Chiltern, Elizabeth Line or London Underground.
In a tweet, GWR said: “Due to damage to the overhead power lines between London Paddington and Slough, some lines to London Paddington have been blocked. Train services running to and from these stations may be cancelled, delayed up to 60 minutes or revised.
“Disruption is expected until 8 p.m. Ticket acceptance is in place with SWR, Chiltern, TfL on the Elizabeth Line and London Underground on any reasonable route until further notice.”
National Rail Inquiries shows that all services to and from Paddington have been “delayed” or “cancelled”.
This is the second time in a week that trains from Paddington have been suspended, with Monday services facing the same issue.
