Having first been appointed in 2018, the new deal includes an option to extend the framework for a further two years.

Through the framework, valued at approximately £23 million per year, Balfour Beatty will supply, operate and maintain a fleet of high-performance tamping machines to support track renewal and maintenance projects across England, Scotland and Wales.

The tamping machines maintain the railway network by hydraulically lifting the track and packing ballast underneath the sleepers to fill voids and realign the tracks, ensuring a smooth and stable railway for freight and passenger trains, helping to reduce the number of speed restrictions and line closures caused by defects.

Balfour Beatty’s appointment to the framework builds on the company’s 25-year track record of delivering safe and efficient rail plant services, its commitment to investing in the latest rail plant technology, and its ability to deliver cost-effective and reliable solutions.

The company operates one of the most modern tamper fleets in the UK, with a strong investment pipeline that includes four new state-of-the-art electric machines which are set to enter service between 2025 and 2026; a pioneering move that aligns with its sustainability strategy, Building New Futures, as well as Network Rail’s sustainability and decarbonisation commitments.

Mick Rayner, managing director of Balfour Beatty’s Rail business, said: “We are proud to continue our longstanding relationship with Network Rail, having first been appointed to the Supply Chain Services’ framework in 2018.

“By leveraging our extensive expertise and our unique, modern and sustainable fleet, we will ensure the railway network remains resilient and efficient. Our commitment to innovation and sustainability will help drive improvements, delivering value for both passengers and freight operators.”

Works are due to start in Spring 2025. At peak, Balfour Beatty will employ approximately 110 people.
