The upgrades are crucial to the future operation of Crossrail (Elizabeth line) services as well as the modernisation of the Great Western Main Line.
Alstom’s contract is for the final stage of the full re-signalling of the Great Western Main Line between Reading and Paddington in the west of London. It covers the design, manufacture, supply, installation, testing and commissioning of a train control system. The signalling work, which is already underway, will allow Transport for London’s Crossrail trains to operate on that section of the railway along with other services on the Great Western Main Line.
The £11m contract awarded to Amey for signalling power works between Paddington and Hayes & Harlington includes replacement of obsolete power supplies and new supplies for the signalling equipment. This enables the system to be automatically supplied from separate supplies in the event of a power failure anywhere between two points.
Matthew Steele, Crossrail programme director at Network Rail, said: “This is a vital step in the delivery of a bigger, better, more reliable railway for London and the southeast. 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.”
Amey chief executive Andy Milner said: “We have a long-standing involvement with the Crossrail project, having worked on various parts of the programme over the last five years. This latest contract reflects our position as a trusted key supplier to Network Rail and I am pleased that we can continue support them through the delivery of essential signalling power supply systems on such a significant project.”
Crossrail will be known as the Elizabeth line from December 2018 when services start running through central London. The full route will open in 2019. New trains will allow passengers in west London and Berkshire to travel through central London and out to Essex.
