South Island line
The South Island line (), identified by light green on the MTR route map, is a rapid transit line of Hong Kong's MTR metro system. This line connects the HK business district from Admiralty station to the Southern District of Hong Kong Island and the island of Ap Lei Chau, which was not served by any rail transport prior to the opening of this line. The rolling stock of South Island line is purpose-built for driverless operation. Trains are remotely controlled from the Operations Control Centre in Tsing Yi. Approved by the Executive Council in 2007, the line commenced service on 28 December 2016. This line was known during planning and construction as the South Island line (East) to distinguish from South Island line (West), which is still being planned. History The initial proposal for the line was in 2002, and went through a number of changes, at times combined with the West Island line and South Island line (West). The final alignment corresponds with "option B" of the 2005 revised scheme, with no intermediate station at Happy Valley included, in order to reduce the travel time to the CBD.
