Essential engineering work, including the replacement of track and points, is set to get underway at Slade Green, near Dartford in Kent.
Work on the £4.5m project starts this weekend, with the finished improvements intended to reduce faults and delays at the heavily-used junction, where lines from South East London and Greenwich meet each other on their way to Dartford and Kent.
It forms a key part of the South East Upgrade, where a record £1.25bn is being invested to upgrade track, signalling, structures, earthworks, stations and depots to give passengers better journeys.
For five consecutive weekends from January 16, 2021 through to February 14, 2021, the works will be carried out and will affect train services between Barnehurst/Plumstead and Dartford. Work will also take place on the weekend commencing March 13, 2021.
The current track is nearly 50 years old and is in a critical location to support train performance to and from the depot where trains are stored and maintained.
Works being carried out include the renewal of seven switch and crossing units over 316m of track. Around 2,900 tonnes of ballast will be used during the project and 820 railway sleepers are set to be replaced.
Network Rail’s Route Director for Kent, Fiona Taylor, said: “This investment in our railway is the largest in history and has already delivered major benefits for Kent’s rail passengers.
“For safety reasons, our work often needs to be carried out while trains are not running and we ask our neighbours to bear with us during any disturbance. Rest assured that we will be keeping noise levels to an absolute minimum.”
Scott Brightwell, Southeastern Train Services Director, added: “The junction at Slade Green is a heavily used part of our network and I am pleased that it is being renewed as part of the South East Upgrade.
"It will mean more reliable journeys for our passengers but there will unfortunately be some weekend disruption. A bus service for essential travel will be operating for our customers.”
