The closure of Marylebone station in London remains in place following a cable fire. A statement from Chiltern Railways explaining the problem said:
"Around 2 metres of signalling cable in the tunnel into the station has burned away meaning the signalling system is not working.
"Without signals we cannot safely run trains, so are not running to or from Marylebone until new cables are installed and tested. We are not sure how long this will take, but we may not be able to run until Monday morning.
