Passengers intending to travel on the Mildmay line on London’s Overground network are being warned that could could face several weekends of disruption over successive weekends from Sunday 19th January to Sunday 16th February.

The main cause for this disruption is the replacing points and half a mile of track near Stratford, where frequent passenger and freight services on this section on the Overground system has caused the rails to become worn.

With Mildmay trains not able to reach Stratford, Network Rail have also decided to undertake other projects along the route to future proof against any disruptions in the future.

During the closure of the Mildmay Line track work will be undertaken between Camden Road and Stratford, power supply work will be carried out at Canonbury and 20 wheel timbers (special keys that fix rails to certain types of bridges) will be replaced on Chalk Farm Bridge to the west of Camden Road station. The new timbers have a life expectancy of 50 years.

While this work is being carried out residents along the line or passengers at near by stations which will remain open, may have to put up with noise from these works especially from ballast trains, tamping machines and rail grinders.

Mildmay Line Service Alterations

Buses will replace trains across the closed sections of the Mildmay Line while all these works are taking places. Partial rail services on the line will run but will vary from week to week. Here is a list of what works and services are taking place over the rest of this winter:

Sunday 19 January: No trains between Gospel Oak and Stratford. Also no trains between Willesden Junction and Clapham Junction

Saturday 25 and Sunday 26 January: No trains between Gospel Oak and Stratford

Saturday 1 and Sunday 2 February: No trains between Gospel Oak and Stratford

Saturday 8 February: No trains between Camden Road and Stratford
Sunday 9 February: No trains between Gospel Oak and Stratford

Sunday 16 February: No trains between Camden Road and Stratford

Sunday 30 March: No trains between Camden Road and Stratford

“We’re really sorry for the disruption, but there are lots of vital jobs that we simply can’t get done whilst trains are running. We’ll be making the very most of our time on track to help keep this part of the railway safe and reliable.”

Simon Milburn, infrastructure director for Network Rail Anglia

“This maintenance work is vital to ensure we can continue to operate the most reliable possible service for customers. I would like to apologise to our customers for the disruption and ask them to check before they travel and allow a little extra time to complete their journeys.”

Rory O’Neill, TfL’s General Manager for London Overground

The London Overground network has seen disruptions and celebrations in the past 4 months, most notably the renaming of all the Overground lines and the installation of a new signalling system in South London last October.

Since the start of 2025 other parts of the Overground system have also been closed at weekends so Network Rail can tend to other smaller engineering projects.
