Why so High?
When visitors first come to the DIRFT site, they are surprised that the new railway line has been built on a 9 metre high embankment since the surrounding land is relatively flat. But the embankment is essential because the rail track has to cross the A428 on a bridge that is sufficiently high for large vehicles to pass underneath. The same line will also serve the third phase of Prologis RFI DIRFT, which means that it will need to cross another bridge over the A5 to reach the new site.
The embankment, which runs for 800 metres along the western boundary of the DIRFT site, will also support Sainsbury’s intermodal facility – a 400 metres long by 30 metres wide concrete slab where goods will be unloaded either directly onto trucks or into the warehouse for storage. It will also act as an environmental bund, providing an acoustic and visual barrier between the distribution hub and future residential development.
Because the embankment will carry the railway line to the new phase of DIRFT, it has been designed to carry four lines of track; two will stop at the Sainsbury’s depot, while the other two will carry on through the site, over the A5.
