Key Projects | Longsight, Manchester

Project Scope

Keltbray Rail were contracted to undertake the conversion at Longsight of the fixed tension OLE to auto tension. Contracting direct to Network Rail as their Principal Contractor, Keltbray Rail undertook the design, supply and installation for the OLE and foundation works.
The works comprised of converting two wire runs from FT to AT through the complex area of Longsight.  Included within the scope was ground investigation and composite analysis surveys, full AFC OLE and Civils design, removal of Japanese Knotweed, build foundations into retaining walls, 3m side bearing foundations, signal sighting, design solutions, Tensorex spring tensioners installation, Installation of straight point load cells, installation of section insulators, alterations to Overlaps, re-droppering, bridaling, re-registration for swivel bracket movement.
Additional to the works, Keltbray Rail, at our Crewe office, constructed a purpose built training span to facilitate the training of Manchester Maintenance OLE staff on the installation, adjustment and maintenance of the Tensorex spring tensioners and load cells.
This was a key contract for Network Rail and was within the top 3 priority contract completions at Christmas 2012, with the successful installation and commissioning of the works this allows Network Rail to increase the line speed by an additional 10 mph in one of the most important and congested areas of the network in the northwest if not the country.
The completion of these works once again shows that Keltbray Rail can deliver a very complex Overhead Line scheme including design, supply, build and commission to time and budget.
