Key Projects | Power Supply Upgrade 3A

Project Scope

Keltbray Rail was awarded the contract to provide Power Supply Upgrade (PSU) Phase 3A Along Track Works by Network Rail.  The two and half year contract commenced in January 2012, as part of Network Rail’s 10 year investment programme, to provide a more efficient and environmentally sustainable rail infrastructure.
Keltbray Rail are constructing the Overhead Line Electrification (OLE) incorporating design, civils, signalling and de-vegetation works. The overall programme will be completed in March 2014 from our facilities in Crewe and Rugby.
The main works comprise of installation of 8,500 insulators on OLE structures, 192km of Return Screening Conductor, 391km of ATF Conductor, Removal of 193 Boosters including 23 full structures, Conversion of 181 No insulated overlap to non-insulated overlaps, Conversion of 137 No 8KA to 12KA switches and installation of high voltage cable solutions at 50 Overbridges and 4 major Tunnels.
Working with our client a number of innovative areas have been developed including:
  • Accelerated design processes – improving efficiency, review and sign off times.
  • Our focus on operational efficiency enables us to install 3km of RSC (return screening conductor) in restricted midweek night possession – a first in a project of this type.
  • Our development of innovative plant solutions has developed a new solution which enables us to install under tension 3.6km of overhead wire in a single shift.
The works once commissioned will give an increase capacity of the WCML in order to meet the new proposed timetable increases from 2014 onwards.
