The Barking - Gospel Oak Line User Group has some interesting information on the London Overground-related improvements planned for the line. Highlights:
- The new trains to be introduced in 2009 are Class 172 Turbostars. These are the same as are being ordered by London Midland, and presumably TfL saw an oppurtunity to get in on the order. Unlike current Turbostars, they use the lightweight bogies currently seen on Virgin Voyagers, and the lower weight gives improved acceleration away from stations. Each carriage is 23m long, vs 20m for the current Sprinters.
- Four trains per hour from December 2009, though whether any will run beyond Gospel Oak isn't mentioned.
- All stations staffed, and ticket machines at every entrance.
