Transport for London said London Underground tickets will be accepted on South Western Railway, C2C and local bus services.
Meanwhile, there are severe delays between Highbury & Islington and West West Croydon/Clapham Junction/Crystal Palace/New Cross on the London Overground, with minor delays between Stratford and Richmond/Clapham Junction. The rail operator said this is because of a shortage of trains caused by "extra safety inspections", after debris was discovered on the tracks last night.
London Overground said it is "working flat out to resume the full service".
