Company overview

Overhead Line Engineering Ltd (OLE Limited) is a Derby-based railway engineering and electrification design consultancy.

The firm provides a range of overhead line engineering support services, working across the entire project lifecycle – from inception, design, construction, and commissioning, to equipment renewals and upgrades.

Its experienced team has an understanding of all types of UK OLE – including ex-DC systems, the latest UKMS range, and the Network Rail Series 1 OLE system. This enables it to support almost any project.


OLE Limited’s approach is underpinned by value engineering techniques, which streamline projects while delivering client objectives and complying with industry standards. The company works closely with a well-established supply chain, meaning it can provide multi-disciplinary design packages.


OLE Limited supports a range of high-profile rail organisations, including Volker Rail, AECOM, and SPL Powerlines Group. It has also been appointed to provide allocation design and consultancy services directly to Network Rail.
