Network Rail’s £5 billion ‘next generation’ track works contracts is inviting bids through a contract notice. The suite is the largest of its kind being undertaken in the upcoming funding period, control period 6 (CP6), which runs from 2019 to 2024.

The contracts cover 10 years of railway track works and will introduce three new geographically-focused alliances between Network Rail, designers and construction suppliers. The alliances include: the North Alliance (Scotland Route); Central Alliance (London North West, London North East and East Midland routes) and the South Alliance; (Anglia, South East, Wessex, Western and Wales routes).

Each alliance will combine the development, design and delivery of plain line track and switches and crossings, as well as associated infrastructure works for each area. The step sees plain line and switches & crosses brought together operationally and commercially as a means of delivering infrastructure works more efficiently and effectively for customers, said Network Rail.

This move is a key part of the Rail’s Infrastructure Projects CP6 procurement strategy, which aims to promote collaborative arrangements with the supply chain that offer better value for money for devolved route customers.

“Combining our plain line expertise with that of switches & crossings will bring huge benefits to both our route customers and the wider supply chain. The proven alliance model offers a flexible and cost effective solution with a greater focus on each route’s specific requirements and needs,” said Steve Featherstone, Network Rail director for track.

The pre-qualification period for the tender will start in June.

Network Rail owns and operates the railway infrastructure, including 20,000 miles of track, 30,000 bridges and viaducts and thousands of tunnels, signals, level crossings and points, in England, Wales and Scotland on behalf of the nation. It also manages rail timetabling and 20 of the largest stations in England, Scotland and Wales.
