London Overground passengers can expect disruption to journeys over the festive period due to track replacement work.
From 27 December until 4 January, Mildmay line trains will not run between Camden Road and Richmond/Shepherd's Bush but a special train service will run between Willesden Junction and Stratford via Queen's Park.
On Boxing Day there is a shuttle service only between Shepherd's Bush and Clapham Junction.
Simon Milburn, from Network Rail Anglia, apologised for the disruption, adding: "But this is a big job that will make a real positive impact for passengers in the long-term."
Engineers will be replacing 10 sets of points, which are the movable sections of track that allow trains to switch from one line to another.
The points are currently in poor condition and are held in place by deteriorating timber sleepers, Network Rail says.
There will be further disruption on the weekends of 10-11 January, 31 January to 1 February and 14-15 February to complete the installation after the new track has settled.
Railway replacement buses will run throughout the engineering work.
Mr Milburn added: "The busy Mildmay line is shared with regular heavy freight trains, which means there's more stress and strain on the track than on other parts of the network.
"We are installing new track that is built to last for decades to come."
