East London Line
Works are progressing well on our Railway Electrification contract for Transport for London (TfL) to provide power supply infrastructure to the London Overground East London Line (ELL) Phase 1A extension from the existing buffer stops at Dalston Junction through to the Network Rail infrastructure interface at Highbury.
The design, build and commission contract involves the provision of a modular build 750V DC traction substation with associated rail power system infrastructure such as cable routes, conductor (3rd) rail, tunnel lighting, signalling supplies and SCADA.
In parallel with the design and construction works, system integration of earthing and bonding, EMC and stray current collection systems needs to be managed on an interdisciplinary basis across the project. As a result the contract scope requires a stringent interface management process to address the technical requirements within the project. In addition to the project interdisciplinary coordination these interfaces also include the boundary interface with ELL Phase 1 supplies, the parallel running of Network Rail 25kV North London Line, and the boundary interface with Network Rail infrastructure at Highbury traction substation, incorporating an existing 750V DC – 25kV AC Transfer Track.
The challenging technical and logistical scope requires an experienced design and construction management team, sourced from Huntly Road and Greenwich offices and led by project manager Duncan Hall, to deliver the scope to target and provides additional depth to the established Power Systems portfolio of traction power system design and build capability.
