Rail services in and out of London Marylebone could be severely disrupted until the end of service tomorrow, National Rail has warned, due to a cable fire earlier today.
The rail service said it is "not known how services will be affected tomorrow", but disruption is expected to continue until the end of the day.

"A cable fire between Wembley Stadium and London Marylebone has damaged signalling in the area and all lines are blocked," said Chiltern Railways.
"The disruption is expected to last throughout Tuesday 4 October and we are assessing the situation for Wednesday 5 October.
"Chiltern Railways tickets are being accepted on Virgin Trains, London Midland, CrossCountry and Great Western Railway via any reasonable route."
The rail operator has provided advice on how to deal with the service disruption, including alternative routes, and warned that "several trains will be cancelled completely in order to reduce queues of trains" on southbound routes heading into Marylebone.
