VolkerFitzpatrick has commenced construction on the first phase of the Radlett Strategic Rail Freight Interchange (SRFI) for SEGRO, a leading developer and manager of industrial properties.

The new facility will be connected to the Midlands Mainline (MML) via a dedicated two-track rail link.

Currently, VolkerFitzpatrick is executing a multi-million-pound rail contract that includes building a new underpass, installing overhead line equipment, lineside civils, and adding switches and crossings for the MML connection. The underpass is a critical element, as it will accommodate the two-track rail line feeding into the new terminal and support the future construction of warehousing facilities.


To install the new 60-metre precast underpass structure, currently being constructed next to the rail line, VolkerFitzpatrick is using Freyssineyt's unique and complex cabling system that has been constructed underneath the concrete structure. When complete, the underpass structure weighing over 6000 tonnes, will slowly be moved through an excavation under the rail line during a Network Rail 9-day blockade over the 2024 Christmas period.

The rail line will remain open for much of the duration of the whole project, with the majority of possessions being carried out over night to minimise disruption to passengers. Meticulous planning and co-ordination has been established to enable the completion of the tight timeframe.

VolkerFitzpatrick is also committed to being sensitive to the surrounding community and have implemented a range of measures to minimise disruption, including strict noise control protocols, dust suppression techniques, and maintaining clear communication channels with residents.

The project also includes junction improvement works, a new roundabout on the A414, landscaping and rail works.
