Complementing the City Class Tram and LR55 light rail technologies, Tram Power has also developed and proven a unique technology for a lighter Over Head Line (OHL)  system.
This can help to reduce the cost and the lead time of implementing Light Rail schemes. The Trampower OHL was recently granted a European Patent.

  • Electrical – low resistivity from larger cross section conductor.
  • Mechanical – can stand loadings from wind, weather and pantographs.
  • Capital cost – reduction through fewer parts.
  • Single OHL wire – with equal pressure sag.
  • Large diameter (14mm) (150mm²)
  • Fewer support masts – typically 50m spacing.
  • Simple suspension systems – no registration arms.
  • New simpler tensioning.
  • Suitable for speeds up to 150 km/h.
  • Low cost electrification and communications for secondary rail lines.

International Recognition for Trampower Simplified OHL

The simplified  OHL developed by Trampower and tested at the Carnforth Railway Centre, has now been internationally recognised, with the granting of British, European, French German and other patents. It has also been used for the recently opened Metrolink extension to Ashton and the Nottingham second phase to Beeston. Other installations are expected to follow, including the GUILD Line in Preston. The Trampower OHL provides  the performance of a conventional catenary at the lesser cost of a single wire system.
