Our Electrification and Plant team have a strong capability for undertaking overhead line related design work. With one of the UK’s largest design resources, our highly skilled electrification and design consultants cover all the Network Rail GRIP stages – to include feasibility study, outline and detailed design, technical support to construction.

Our Overhead Line (OHL) survey specialists have access to the latest point cloud technology to conduct Overhead Line Equipment (OLE) site inspections. This allows for safe and efficient collection of data via a laser scanning method, removing the need to revisit the survey in future whilst providing extremely accurate information.

Our design team have previously undertaken work to modify existing OLE infrastructure and support new electrification schemes such as providing detailed design for the Great Western Electrification Project (GWEP) and auto-transformers design for West Coast Main Line.

We advise on overhead bridge clearance issues relating to the modification of existing overhead electrification. Our experienced consultants can produce design and consultancy documents relating to these changes and offer tailored expert advice in line with our client’s requirements. We have also undertaken OLE de-wirement incident investigations in the UK and overseas.
