Overhead Lines

Our Overhead Line (OLE) design capability ranges from asset condition surveys and feasibility work through to design, complex modelling and construction support on major schemes such as the Transpennine Route Upgrade works. We have the ability to deliver OLE projects of all sizes, from major renewals to minor maintenance works.

Our OLE Design Engineers utilise the latest CAD software in order to produce 3D BIM compliant models for a range of GRIP/PACE stage design drawings, and we have developed our own automated design software that automatically draws and updates designs in real time.

Our team has a nation spread over 5 locations from Swindon to Manchester via Cardiff, Birmingham and Derby. With over 60 engineers at our disposal, we have the knowledge and capacity not only to deliver conventional OLE designs, but to challenge the norm, leading us to develop new Permanently Earthed Section (PES) designs, which in conjunction with the latest Tri-Mode trains, allows electrification of the railway at much reduced cost by removing structural clearance issues, whilst providing the added benefit of a considerably lower capital carbon footprint.

The OLE team’s services include:

  • Height and Stagger surveys
  • Feasibility Studies
  • Outline Designs
  • Detailed Designs
  • OLE design for complex station areas
  • OLE design for open route
  • Design of Permanently Earthed Sections
  • Construction support
