We were awarded the design and build contract for the Silwood Sidings Permanent Way and Civils works as part of the London Overground Capacity Improvement Programme (LOCIP). These works were essential in meeting the commitment made by former Mayor of London, Boris Johnson to have five car trains running on London Overground by the end of 2014.

 

The project involved taking the scheme from GRIP stage 4 through to GRIP stage 8, with the installation of stabling sidings for 10 five-car trains, a new signalling system, traction power and staff welfare facilities. These works formed a vital part of the 25% capacity improvement programme to carry more passengers and reduce congestion.

 

The Cleshar project team managed the design and construction of the 10 new roads, including a turnout from the mainline and a crossover between the existing mainline tracks.

The design and installation of the sidings posed significant technical and logistical challenges in the tight brownfield inner city site. The project team worked closely with the LOCIP delivery team and, by the time that the traction power systems were commissioned in May 2014, more than 180,000 hours of labour had been recorded in delivering the project.
