Did you know that Dover is the first MRT station in Singapore to be built along an existing line?
Dover station of the East-West Line opened on 18 October 2001 and is the first station in the MRT system to be built on a live section of a train line.
Train services between Buona Vista and Clementi continued to run during the construction of the station, making it a challenging task for the engineers to carry out works without disrupting services. The construction work could also only be carried out mostly at night to minimise disruptions to the students of Singapore Polytechnic.
Trains would have to slow down within the construction zone, while a steel tunnel was used to prevent debris from falling onto the tracks, which could potentially disrupt train services.
Similar to Dover station, Canberra station between Sembawang and Yishun on the North-South Line is the second station to be constructed along a live MRT line, and opened on 2 November 2019.
A third station that is currently under construction on an existing line is Hume station, between Hillview and Beauty World of the Downtown Line. Although the station is not fully completed, the structural works for the station box were constructed together with the rest of the Downtown Line Phase 2. Thus, the station only requires full interior outfitting works and additional alteration work for its expected opening by 2025.
By 2040, two additional stations will also be constructed along the North-South Line; they are Sungei Kadut (between Yew Tee and Kranji) and Brickland (between Bukit Gombak and Choa Chu Kang) stations.
