The connection to the depot will allow trains to be housed and maintained there and ease congestion of East-West Line trains.
The four-in-one depot will house trains from the East-West Line, Downtown Line and Thomson East-Coast Line, as well as buses at a bus depot.
While the engineers were working on the tracks, more than 280 staff from LTA, SMRT, and SBS Transit were deployed to help commuters in their journeys, such as by ushering commuters to shuttle buses.
Two shuttle routes have been operating between affected stations to maintain connectivity.
