Global Rail Construction were selected by Siemens as design and build civil engineering contractor for a Horizontal Directional Drill (HDD) that was required to cross under a Grade 2 listed building, the Great River Ouse, Ouse Road and the East Coast Mainline railway in the heart of Selby town centre.
Utilising their in-house multi-disciplinary design team, Global Rail Construction were able to offer Siemens a complete design and build solution.
The civil engineering works, which formed part of the Selby Rail Swing Bridge Signalling Interlocking Renewal being undertaken by signalling product specialist Siemens, were being specifically undertaken to renew the existing electricity cables, which had been installed in 1956 and were located under the river.
The project consisted of the replacement of the swing bridge cabin signalling interlocking onto a new interlocking building, incorporating new lineside equipment from locations 128, 129, 130 and 131, which also required cables to traverse into the river at this location. The conventional approach of simply running the signalling cable across the bridge was not appropriate, as one 40m span of the swing bridge – which was built in circa 1900 – allowed river traffic to pass. Hence, Global Rail Construction designed a suitable ducted solution to carry telecommunication, signalling and power cables on behalf of their client.
