More delays have hit the troubled £130M Gospel Oak to Barking electrification project after Network Rail postponed an announcement on further work.
Design blunders meant that work on the 22.4km stretch of London Overground line was not complete when it opened in February, and more weekend work and full closures were promised for later this year.
But Network Rail, which is delivering the project, has now postponed an announcement on dates for future closures after admitting it needed more time to agree plans with Transport for London (TfL) and the Department for Transport (DfT), which are funding the scheme.
“We had hoped to be in a position to confirm future closures by the end of April,” said a spokesperson for Network Rail.
“We will share our plans, including details of when the railway will need to be closed, as soon as they are confirmed.”
According to Network Rail, initial delays were caused by design faults on structures needed to carry the overhead lines, which could not be installed as a result. Late delivery of materials also contributed to the delay.
A review into what went wrong on the electrification scheme began in February. TfL has said it is seeking compensation from Network Rail for the delays.
“We continue to work with Network Rail to understand how they will complete the remaining work to electrify the Gospel Oak to Barking line with the absolute minimum further disruption to our customers,” said TfL director of London rail Jonathan Fox.
“A number of options are being considered and we will make a more detailed announcement in due course when Network Rail can assure us that plans to complete the delayed works are robust.”
