UK infrastructure manager Network Rail (NR) has awarded a £79m contract to Alstom for the final stage of a signalling system, which will control trains between Reading and Paddington.

As part of its contract, Alstom will be resposible for design, manufacture, supply, install, and testing of the system.

NR has also awarded a £11m contract to UK-based Amey, which will replace obsolete signalling power supplies between Paddington and Hayes & Harlington with resilient systems. These will be able to automatically switch between separate supplies in the event of a power failure.

The contracts were awarded within NR’s existing framework agreements and form part of the ongoing GWML modernisation and Crossrail projects. According to NR, the upgrades are crucial to the future operation of Elizabeth line (Crossrail) services, as well as modernisation of the Great Western Main Line (GWML).

Alstom is working with NR to develop an interlocking system based on its Smartlock range. Smartlock interlocking solutions have been developed for complex and challenging major railway re-signalling projects.

This technology will be supplied ready for European train-control system (ETCS) installation, allowing locomotives with ETCS capability to operate on that section of the line.

Work includes both renewal of existing Interlocking and track remodelling. It has started in order to maintain the tight delivery programme and is due to reach completion by the end of next year.

"We increase the capacity and reliability of the railway meaning that passengers benefit from quicker and easier journeys they can depend upon."

Network Rail Crossrail Programme director Matthew Steele said: "This is a vital step in the delivery of a bigger, better, more reliable railway for London and the south-east.

"By ensuring the new trains can run seamlessly amongst existing rail services and by building in resilience at the outset, we increase the capacity and reliability of the railway meaning that passengers benefit from quicker and easier journeys they can depend upon.

"To deliver this work in the safest and most efficient way possible, we need to make the most of the huge potential within our supply chain. So we look forward to continuing our close collaboration with Alstom and Amey in the delivery of these crucial elements of the Great Western Main Line upgrade and our preparation for Elizabeth line services."

It is reported that the signalling work will allow Transport for London’s Elizabeth line trains to operate on that section of the railway, along with other services on the GWML.
