The Gospel Oak to Stratford section of the London Overground service will be closed between Saturday 20 February and 1 June 2010 to allow major engineering works to take place, Transport for London has announced.
The work includes efforts to improve signalling and track as well as platform lengthening and forms part of a £326m upgrade of the London Overground service.
Bosses at TfL promise the work will herald a new era of more frequent services with longer trains.
Ian Brown, the Managing Director of TfL London Rail, said: “We apologise to passengers for this inconvenience and are doing all we can to minimise the disruption caused. This was one of the most neglected railways in the UK when we took it over two years ago and these are essential works that will help us unlock the true potential of the London Overground network, which is to offer a far more frequent Metro-style turn up and go service.
“We have to close this part of the line for this amount of time because of the nature of the work. Large amounts of material will have to be moved around for the signalling and track upgrades, which means if we were to restrict the work to weekends and then have to restore the railway to working order each Monday morning, the disruption would be over a much longer period.”
For the duration of the closure a rail replacement service will provide buses every 20 minutes six days a week. On Sundays this will reduce to two buses an hour.
