Travellers travelling to and from London on the East Coast Main Line are experiencing delays and disruption to services following problems with overhead power lines.
Rail services on the East Coast Main Line have been severely disrupted by problems with overhead power lines.
East Coast, Grand Central and First Hull Trains are starting and terminating at Peterborough, meaning they are unable to run between Peterborough and King's Cross.
First Capital Connect are running shuttle train services between Letchworth Garden City and Cambridge, between Biggleswade and Peterborough and between Welwyn Garden City and King's Cross.
Buses are replacing trains between Letchworth Garden City and Welwyn Garden City and between Letchworth Garden City and Biggleswade.
Trains between Stevenage and Luton and between Stevenage and Hertford North are also being replaced with trains.
Rail services on the East Coast Main Line are expected to resume again after faults with overhead power lines caused major disruption.
There's not such good news for people wanting to travel between Welwyn Garden City and Letchworth as trains there are due to be disrupted for the rest of the day.
Services between Cambridge and King's Cross are also expected to be disrupted for the rest of the day.
It's not yet known what caused a series of problems with overhead power lines.
Services between King's Cross and Peterborough have begun again after thousands of commuters suffered delays caused by overhead power line problems.
King's Cross station was full of commuters on Monday night, after delays caused by overhead wire problems between Stevenage and Hitchin.
Soon after 2.30pm yesterday damage was found to overhead power cables on three lines around Hitchin. This damage was confined to the wire itself and not the structures, but was significant enough that we had to stop traffic through the area.
By 6.30pm we had two lines through Hitchin open allowing limited services to run. The route to Cambridge remained blocked, although passengers from London were and are able to reach the town via Liverpool Street.
From 1am to 5.30am we had just one line open through the affected area, with diversions via Hertford, while the damaged wire was replaced.

We handed the line back at 6.3am and when the first train went through at 6.54am, further damage was found.
The nature of the damage means we have had to close all lines through Hitchin and we are continuing to repair the problem and investigate the cause.
Network Rail would like to apologise for the disruption to people's journeys during this period and we are working hard to fix the problem.
Please do check with your train operator before travelling as there are diversions in place.
