Network Rail said the fire, near South Hampstead, north London, damaged signalling equipment.
The power supply to Euston station was temporarily cut as a result of the incident, leading to the evacuation.
A limited service began to run soon after 7pm, with a London-Manchester train, but passengers were told that, any trains departing London Euston station are likely to be very busy that night. They are advised to travel via an alternative route or delay their journey until the next day.
Some passengers who were on trains heading for Euston when the fire broke out reached the station over three hours late.
Virgin Trains, which runs services to Birmingham, Liverpool, Manchester and Glasgow, said that, customers are able to use alternative routes where available but are advised to check before travelling.
Other train operators, including East Midlands Trains, Chiltern Railways, Virgin Trains East Coast, Northern, Transpennine Express and Great Western Railway “are conveying passengers via any reasonable route until further notice,” according to Virgin.
Disruption is likely to continue until the end of services around midnight. London Underground services did not call at Euston in order to ease crowding.
National 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.
