Clayton Tunnel North – TP Hut

Contract value:

Structural & Civil Engineering

At Clayton Tunnel North we designed a new modular TP Hut. This will enable the greater regulation of traction current between Hassocks and Pangdean Sub-stations.

Situated adjacent to an access track, and well above track level a purpose designed cable ladder has been installed to carry all cables between track and TP hut. Flexible ducts carry cable below an existing signal troughing route, thus facilitating future cable laying.

Security fencing encloses the TP Hut’s compound and a car parking area. Particular care has been taken to prevent any surface water run off flowing down to track level.  Within the compound reinforced a concrete raft will support the modular TP Hut, which was delivered as one unit.
