The Gospel Oak to Barking line is set for another eight weekends of closures, after delays to electrification due to incorrect design and late delivery of materials.
Network Rail has said the equipment used will mean "some disturbance is unavoidable" for locals, but that it will make "every effort" to minimise any unnecessary noise.
Additionally, these eight weeks won't be the end of the closures either, as a full schedule is still being drawn up.
Work began on the £130m upgrade in June 2016. While TfL had originally planned for electrification of the line to finish by the end of next month, it was announced in February that the work had not been finished on time and more needed to be done.
Network Rail said at the time it was pulling together "a robust plan" to complete the work before new trains arrive early next year, which would mean further closures required over a series of weekends and likely involve a full closure for a period later in the year.
It had initially intended to confirm future closures by end of April, but this was delayed. Now the next set of closures for electrification work to continue have been announced:
Caroline Pidgeon, Liberal Democrat member of the London Assembly and leader of its transport committee, said:
Passengers were promised a year ago that the upgrade work would be finally completed by the end of June 2017.
Even with this latest news Network Rail are still not providing details about the expected full closure of the line that will be necessary to complete the electrification work.
Both residents living close to the line and passengers have already suffered enough. It is time Network Rail came clean and gave people advanced notice of the full schedule of works necessary to complete this vital electrification project.
