Rail passengers are being warned of changes to trains in and out of London Euston so urgent repairs can take place after severe flash flooding.
The deluge in the capital on Monday 12 July caused an electricity substation to catch fire disabling London Overground services to Watford.
Urgent repairs need to take place to pump away any remaining standing water and fix cables damaged in the electrical fire.
The work means all lines in and out of London Euston must be closed between 11pm on Wednesday 14 July and 6am on Thursday 15 July. Passengers are being asked to travel early on Wednesday night.
The urgent repairs will impact Avanti West Coast, London Northwestern Railway, Caledonian Sleeper and London Overground passengers at the end of tomorrow and first thing on Thursday morning.
Bus replacement services will be in place to keep passengers on the move and people are being urged to check www.nationalrail.co.uk for the latest information.
James Dean, Network Rail’s West Coast South route director, said: “I’m sorry that your journeys have been disrupted this week. Our engineers will be making critical repairs on Wednesday night.
“The floods made the railway look like a swimming pool, but with 750 volts of electricity running through it. We’ve had to make the site safe before going in and pumping away the remaining flood water and repairing the fire damage.”
