OREANDA-NEWS. A piece of cable came into contact with the overhead wires at approximately 2:45pm on Tuesday. This caused a power failure and loss of signalling, which affected train services.

Network Rail engineers have been on site working to repair the problem, but this work is expected to run into the morning peak, affecting passengers on Thameslink and those using East Midlands Trains into London.

A Network Rail spokesperson said: "Owing to a piece of cable coming into contact with the overhead wires at Luton station there is currently a very limited train service through the area. We are working to repair the problem and get a full service running again as soon as possible, however this work is likely to continue into the morning peak. We apologise for the inconvenience this will cause and advise that passengers use an alternative route where possible and check with their train operator before they travel."

A Thameslink spokesperson said: "We'd like to apologise for the continued severe disruption so many of our passengers are experiencing. We are doing all we can to keep people updated through our web, app and Twitter feed and have extra staff out on the ground."

Notes to editors
OLE (overhead line equipment) is what powers electric trains but in this case the signalling - the traffic lights of the railway - has been affected too
The wires which power trains have 'tripped' but are still intact and have not been ripped down"
