Engineers are working throughout the night at Euston to stop fresh morning rush-hour chaos after a track side fire caused huge disruption on Wednesday.
The small fire broke out on a section of track near South Hampstead station on Wednesday afternoon, which led to commuter mayhem as all Euston services were cancelled.
The blaze caused damage to signalling equipment and led to a power cut that caused massive disruption throughout the evening at one of London’s busiest rail stations.
Network Rail said engineers were preparing to work throughout the night to install 100 metres of power cables with the aim of getting services back to normal.
The rail company could not confirm how long the works would take.
And they said it was not yet clear whether a full train service will be able to run on Thursday, as trains and crew could be out of position after the major disruption.
Alongside trains in London, services along the West Coast line, including trains serving Birmingham, Manchester and Liverpool, were affected in Wednesday’s chaos.
Some travellers on London Midland and Virgin Trains services south of Birmingham were being advised to avoid using the trains at all on Wednesday where possible.
Photos from the scene showed huge crowds of commuters that poured out of the busy station.

Network Rail on Wednesday night said: "An electrical fire at South Hampstead has stopped trains running in or out of London Euston this evening.
"Train customers are impacted in London and the length of the West Coast Main Line, including Birmingham, Manchester and Liverpool.
"Engineers are preparing to work through the night to install 100 metres of 11,000-volt power cables with the aim of getting services back to normal tomorrow morning."
The fire also took out a stretch of the London Overground line between Euston and Harrow & Wealdstone.
A Virgin Trains spokesman said: "Tickets will be accepted for travel tomorrow or a full refund offered. Alternative routes are available but customers are urged to check their journey before travelling."
Network Rail said the disruption was also affecting nearby terminals, such as Clapham Junction to the south west, and Milton Keynes Central in the north west.
