West London line passengers will benefit from an increased service next year, with four trains an hour all day, every day between Clapham Junction and Willesden Junction, via Shepherds Bush. From May 2010, half of these trains will continue through to Stratford.
The programme includes signals upgrades, track renewal, the lengthening of 30 platforms and station improvements. London Overground will run up to eight trains an hour during peak times on parts of the network when the upgrade is complete.
New and longer platforms at some stations will allow more carriages per train, which will increase capacity and reduce overcrowding.
TfL London Rail’s managing director Ian Brown said a total of £1.4billion was being invested in London Overground.
He added: “A fleet of 32 new trains will enter service from 2009 with more capacity, air conditioning and real time information.”
