Under Track Crossing
Cubis’ under track crossing (UTX) system has been approved for use with Network Rail. This modern method of building an under track crossing creates a faster, safer construction system which reduces track possession times.
The UTX system utilises MULTIduct™ an innovative, lightweight, structural, multiple duct system. The easy to handle 1m long 4, 6 or 9 way units are lightweight under 20kg and offer a unique ‘one click’ push fit connection that is fast and easy to install. Excavated material can be reused during re-installation reducing time, cost, heavy plant and disposal of excess material.
Seamless Integration
The UTX system seamlessly incorporates Cubis’ STAKKAbox™ access chambers with our cable protection system MULTIduct™.

Burial Depths
Due to its high crush strength MULTIduct™ requires a shallower and narrower burial depth and does not require any concrete or specialist surround. Minimum cover for Network Rail UTXs of 0.6m is easily achievable.
MULTIduct™ has a set of recommended burial depths for various applications. Explore the recommended burial depths for Cubis' 4 Way, 4 Way XL, 6 Way, and 9 Way products for multiple locations here.
