Damaged overhead wires bring Kings Cross services to a halt between Peterborough and Stevenage

Major disruption is affecting rail services between Peterborough and Stevenage and is expected to continue until the end of the day, after overhead electric wires were damaged and came down in the area, according to [1]. The blocked lines mean trains running through the affected stretch may be cancelled, delayed by up to 120 minutes, or run on revised routes, according to [1]. Doncaster station is described as heavily congested as a knock-on effect, which may disrupt other services passing through it, according to [1]. Operators caught up in the disruption include Grand Central services between Sunderland, Bradford Interchange or Halifax and London Kings Cross; LNER services linking Aberdeen, Edinburgh, Newcastle, York, Harrogate, Skipton, Bradford Forster Square, Leeds and Lincoln with Kings Cross; Lumo services between Glasgow Queen Street, Edinburgh and Newcastle and Kings Cross; and Great Northern and Hull Trains services on the same corridor, according to [1] and the trigger material. No services are able to run between Sandy and Hitchin, according to [1], and an hourly train shuttle has been put on between Peterborough and Sandy in its place. Trains that would normally run between Brighton and Cambridge are terminating and restarting at Finsbury Park or London Kings Cross, with passengers needing to change there or at St Pancras International to complete their journey, according to [1]. Rail replacement buses are running between Peterborough and Hitchin, and Great Northern and Thameslink tickets are being accepted at no extra cost between Ely and Hitchin for passengers rerouting via Cambridge or Ely using Greater Anglia, CrossCountry or East Midlands Railway services, according to [1]. Tickets are also being accepted, at no extra cost, on Avanti West Coast between Manchester Piccadilly and London Euston, East Midlands Railway between Sheffield or Leicester and London St Pancras, and Great Northern services between Cambridge and Kings Cross, according to [1]. Passengers can also use London Underground services between London stations at no extra cost for these connections, according to [1]. Given the scale of the disruption, LNER is advising customers not to travel today at all, according to [1]. Anyone who wishes to defer can use today's ticket tomorrow, Monday 17 August, without needing to amend it, according to [1]; fee-free refunds are available directly through ticket retailers for those abandoning travel altogether, according to [1]. The cause is overhead line equipment carrying high-voltage electricity, which requires extensive safety checks before repairs can begin, according to [1]. Recovery work can be complex and take time, particularly where multiple sections of equipment are damaged, according to [1]. The disruption lands in the middle of a difficult week for Britain's railways. It follows two separate train derailments in 24 hours: one near Lewes in East Sussex on Thursday, in which two people were seriously injured when three carriages of a Southern Rail service came off the tracks, and a second near Wickford in Essex on Friday, involving a Greater Anglia train travelling from Southend Victoria to London Liverpool Street, according to [2]. Lines near Lewes remain closed between Lewes and Haywards Heath, and services between Liverpool Street and Southend Victoria remain cancelled or curtailed, according to [2]. The Rail Accident Investigation Branch is investigating the Lewes derailment, according to [2]. What to watch next: whether Network Rail engineers can clear the Peterborough–Stevenage damage before Monday's Monday-morning commuter services, and whether today's deferred tickets create fresh congestion on the East Coast Main Line tomorrow.
