Mandai Depot - Trackwork Begins

Commencement of the line's largest system-wide contract, led by CTCI for the design, supply, construction, testing and commissioning of trackwork and third rail system, took place this quarter with the staging ground prepared at the Mandai Depot. This is the second back-to-back trackwork project awarded to the Taiwanese contractor, with a smooth transition of resources expected from the recently completed Downtown Line 3.
