Mainline Trackworks

Trackworks at the depot have been ongoing for over a year now, with majority of the works mostly completed across the depot. CTCI has begun taking over access along the completed portions of tunnel between T206-T208, with trackworks commencing along the reception tunnels 1&2 towards Sembawang Airbase. The permanent tunnel structure within the launch shafts are being constructed over as a conclusion to the civil works.
