Product Solutions

In the trackbed construction, Network Rail specified the use of the TERRAM PW1 trackbed separator to maintain separation between the sand/subgrade and ballast layers. 

Terram PW1 trackbed separator prevents the upward movement of fine sub-grade particles and the intermixing of ballast with the blanket, which might otherwise compromise track stability and performance.

Terram PW1 Trackbed separator is suitable for use in good quality granular formations, as well as clays and silts formations in conjunction with a sand blinding.

Key features and benefits of the PW1 include:

  • High strength and elongation at break to maintain separation and extend ballast life
  • Mechanical bonding and thermal treatment for high abrasion and puncture resistance
  • Approved for use by Network Rail under Product Acceptance Certificate PA05/04556

The result

The TERRAM PW1 trackbed separator will help ensure the Beaulieu Park station trackbed remains stable and performs well over the lifetime of the infrastructure. This supports the project’s goals of providing sustainable transportation options and easing congestion in the Chelmsford area.
