Network Rail has confirmed its revised delivery schedule for completing electrification of the Gospel Oak-Barking Line.

NR’s original timetable was knocked off-course earlier this year, after it failed to install all overhead line equipment during a phased eight-month closure of the route that ended on February 27.

Electrification must be completed by spring 2018, when new four-car Class 710 electric multiple units are scheduled to be introduced. Weekend closures will therefore now take place between July 29 and September 10 for outstanding work. Rail replacement buses will run at these times, and regular users of the line will receive automatic refunds on the additional cost of travelling by alternative means (including the Tube).

NR’s interim Anglian Route Managing Director Meliha Duymaz said: “This project has not been without its difficulties. We’d like to apologise for the continued disruption and thank both passengers and neighbours for their continued patience while we finish our work.”
