The South Rail Systems Alliance (SRSA) Tonbridge division has completed a 9-day track renewal blockade as part of the fifth phase of Network Rail’s Wokingham Re-Signalling programme.

With the SRSA’s input delivered over two phases, our team was tasked with overhauling the double junctions historical interlocking system with modernised switches and crossing (S&C) units to complement the new signalling infrastructure.

These upgrades will improve the overall experience for operators of the rail network, ensuring the network remains reliable, easy to maintain and that the passenger is put first.

Other works included the part renewal and reinstatement of the double guard boarding across the down sidings, cut backs of Conductor Rail to ensure safety and compliance as well as switch outs of HV feeders during possessions.

These works were subsequently section proved with Eastleigh Electrical Control Room before handed back to the client.

Utilising our On Track Plant fleet, our Kirow Crane was called into action during the phases to assist with lifting the point ends in, navigating through compact conditions.

Our Tampers entered site to finalise the installations to ensure the track quality was of the highest quality. While our Freight division were charged with delivering and removing materials and spoil to and from site.

The SRSA is comprised of Colas Rail, Network Rail and AECOM, an alliance created to deliver a portfolio of works across the southern region of the UK over a 10-year period.
