Silwood Triangle Train Sidings

Closed 4 Nov 2012

Opened 15 Oct 2012


Consultation on plans for TfL site at Silwood

In line with the Mayor’s 2012 manifesto, London Overground trains will increase from four to five carriages by December 2014. To support these new, longer trains, we are proposing to build train sidings in Silwood Triangle.

London Overground has become one of the UK’s most reliable rail services. As passenger numbers continue to rise, the service is approaching capacity. Demand on London Overground has grown by 110% in the last 4 years, 180% when the new East London Line is included. Capacity was doubled in 2010 to 2011 but trains are as full now as they were before. Further demand growth of 34% is forecast by 2020. To ensure London Overground continues to provide a high level of service as demand grows, Transport for London (TfL)  is looking at ways to increase capacity. This continues our current investment programme, which will see the new connection from Surrey Quays to Clapham Junction open in December 2012.

What are sidings?

Sidings are used to store trains overnight when they are not in service. Trains will arrive at night and leave in the mornings when service starts.

What is the site currently used for?

An area of the site is currently used as a maintenance yard for our contractors and some of the site functions as a car pound. The rest of the site is unused.

What are you proposing to build?

We are proposing to build signalling and tracks, concrete retaining walls, fences and small buildings that will eventually house welfare facilities for staff. We will also be looking at ways to improve the overall site and the area immediately around it, to make it a greener, more attractive environment. We will investigate opportunities for landscaping in the area.

There will be no large buildings to shelter the trains. Trains will rest on new tracks that will be connected to the existing line.

TfL would welcome your feedback on these proposals.

Key Dates

Our current plans for applying for planning consent and construction (if approved) are:

  • 15 October 2012 to 4 November 2012: TfL consultation before submitting our planning application
  • November 2012: Submission of plans to London Borough of Lewisham
  • February 2013: Approximate date for decision
  • February 2013: Landscaping and preparation of land
  • June 2013 to February 2014: Construction of facility
  • February/March 2014: Facility becomes operational 

If the plans are approved what will happen during construction?

As set out in the Construction Code of Practice agreed with London Borough of Lewisham, TfL and our contractors will work to keep any disruption to a minimum.

The area will take between two and three months to prepare before tracks can be laid. This process will result in some noise, caused by excavation and by heavy goods vehicles arriving and leaving. This preparation work will take place during normal working hours, so we do not expect there to be any evening and night disturbance. Site access will continue to be via Landmann Way, avoiding residential streets.

Once the area is ready, the facility will take between six and seven months to build. This will include the installation of tracks, fences, small buildings and security arrangements.

At times, deep excavations and piling will occur. Should this kind of work take place out of hours, we will aim to notify residents overlooking the site at least two weeks in advance. 

What will the facility be used for?

Trains will be stored at the new sidings. There will be no maintenance or washing.. The area will retain its current use as a depot for track maintenance tools and machinery.

Workers will be encouraged to arrive at the facility using alternative transport methods.

How will you keep the area secure?

Safety is a priority. The area will securely fenced with a security guard on site to control access. It will be fully monitored via CCTV connected to our security centre at New Cross Gate Depot. Unauthorised access will trigger a security alarm. This is the same system currently used in our New Cross depot and we have had no issues with false alarms or lighting at that site.

Once operational, how will the site affect me?

The site will be lit at night, but lighting will be positioned and designed to minimise leakage. Drivers will arrive early in the morning to start the trains. Trains would return to the sidings late in the evenings.

The site will retain its current use as a maintenance yard for our contractors.

What other improvements are being made to London Overground?

These proposals form part of a larger investment programme in London Overground. The full programme will include a range of capacity enhancements across all routes to enable longer and in some cases more frequent services to run.

This continues the recent investment in the network, that will see a brand new connection to Clapham Junction open in December 2012.
