'Rats' cause misery for London King's Cross commuters
Rats could be to blame for a power supply problem that caused travel chaos at one of London's busiest stations, Network Rail has said.
Thousands of passengers had their journeys severely disrupted when a damaged cable knocked out signalling equipment in north London on Monday.
Trains were unable to leave King's Cross station for about two hours during the evening rush hour.
Network Rail said rodent damage had not been ruled out as the cause.
Passengers suffered major disruption as services were cancelled when the power failed just after 18:00 BST.
Some people reported being sat on trains inside the station, which is used by 45,000 passenger a day, for up to four hours.
A Network Rail spokesman said: "A damaged power cable knocked out all signalling between Holloway Road and Finsbury Park, causing severe disruption for passengers travelling from King's Cross station for the rest of the evening.
"While the precise cause of the fault has not yet been determined, rodent damage is not being ruled out."
He added that they do have measures in place to help prevent this but rats do find their way in every now and then.
By 20:00 BST some trains started running very slowly through the affected area and the cable was repaired before midnight allowing a full service to run on Tuesday.
