Network Rail is carrying out work to electrify the Gospel Oak to Barking route as part of the Railway Upgrade Plan.
This programme of works will double the current capacity for passengers on the line and improve air quality for people who live and work near the railway.
From spring 2018, new four-carriage electric trains will provide double the current capacity so that twice as many people can travel comfortably on this route.
This project is part of our London Railway Upgrade Plan, creating new connections and increasing capacity in peak hour by 30%.
The line will close from Sunday 17 September for five weeks, reopening for weekday passenger services on Monday 23 October, weekend closures will continue.
Discussions are ongoing with TfL, train and freight operators to finalise agreements for additional weekend and longer closures from the end of October onwards to complete electrification work. A second, longer closure is currently proposed from Saturday 25 November until Sunday 14 January 2018, however these dates are subject to change. Details will be confirmed nearer the time.
The electrification installation will be completed in January 2018, enabling testing of the new trains and so that driver training can begin. The new trains will start entering passenger service from spring 2018. Current diesel services will continue to run as normal until then.
Passengers should check before they travel and plan their journey in advance at tfl.gov.uk
