Partnership delivers UK’s first 125mph switches and crossings handback

The S&C North Alliance have completed a 125mph line speed handback on an East Coast Main Line switch and crossing project.
Traditionally, ballast needs to settle after renewal projects and speed restrictions are put in place to help the ballast to consolidate safely under normal rail traffic. In this case, the S&C North Alliance team used a combination of advanced engineering techniques to ensure the ballast was compacted within the weekend work, eliminating the in traffic settling period.
“This approach is used routinely on track renewals but this is the first time it has been successfully completed on a switch and crossing project in the UK”
Neil Johnson, Alliance Director at S&C North Alliance, explains: “Switches and crossing schemes are already complex, and delivering a line speed handback brings the additional challenge of ensuring absolute precision at every stage of the project; we maximised the use of existing technology and techniques to achieve this.
This approach is used routinely on track renewals but this is the first time it has been successfully completed on a switch and crossing project in the UK and is a testament to the hard work and expertise of our team.”
Switches and crossings handback at line speed will help prevent delays
According to the Alliance, the ability to handback switch and crossing projects at line speed will help prevent delays associated with speed restrictions – particularly on high speed routes like the East Coast Main Line. Increased accuracy during installation also helps the track perform better, improves reliability and makes it easier to maintain in the long run – therefore reducing the whole life cost of the asset.
Steve Featherstone, Network Rail’s Programme Director for IP Track added: “Being able to handback switches and crossing projects at line speed means better track quality, significantly less disruption and better passenger journeys. This latest achievement is just one of the major milestones reached by the team and I’d like to thank them for their great work over the weekend.
The news follows a number of other 125mph line speed handback achievements for the industry including; high-speed handbacks of plain line track in January and high-speed handbacks of high output ballast cleaning operations in September. The breakthrough of now being able to utilise these techniques in a complex switches and crossing setting has the potential to further reduce passenger disruption and save the industry money.”
