PW1 TRACKBED SEPARATOR – Standedge Railway Tunnel (Network Rail)

Network Rail is currently delivering plain track renewals for eight routes, covering the whole of England, Scotland and Wales. One of the most challenging projects within this is the full track renewal through Standedge Tunnel, in the Yorkshire Pennines, mainly due to the natural height restrictions and the shallow placement of the catch pits.

The solution for Network Rail came by using the TERRAM PW1 Trackbed Separator geosynthetic. The cost–effective product is specifically designed for the rail industry and offers high performance, with its ability to prevent intermixing and improve ground drainage, a key recommendation for the Standedge Tunnel site.

The PW1 geosynthetic is also ideal for preventing the loss of rail track alignment caused by sub-grade erosion, negating the need for longterm costly maintenance procedures caused by having to plan and temporarily close the track for renewal works.
