Client: ABC Electrification Ltd

Year: 2014

Network Rail, the UK railway infrastructure owner, is spending £9bn electrifying hundreds of miles of railway.

As part of the National Electrification Programme (NEP) SNC-Lavalin has been engaged on several packages of work including the West Coast Power Supply Upgrade (WCPSU) for ABC Electrification Ltd. SNC-Lavalin undertook outline and detailed design for two packages of work under Phase 3B of the WCPSU entailing modifications to the auto transformer feeder for 30km of existing electrified railway.

We undertook a high definition 3D survey of the line of route.  The comprehensive survey output eliminated any requirement for site revisits and enabled the production of robust design deliverables.

Our electrification and civils design team then developed the outline and detailed design deliverables for the modifications needed to the existing catenary overhead line system to achieve the required traction power upgrade.  We designed the requisite mechanical and electrical elements, undertook structural analysis of the existing infrastructure, and designed the cable route including complex bespoke solutions at bridges and other structures.
