context_page_description: 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, 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 of Hong Kong in 2007, the line commenced service on 28 December 2016.
  This line was known during planning and construction as the South Island line to distinguish from South Island line, which is still being planned and made in 2022.
context_section_description: Project Agreements and Entrustment Agreement for MTR South Island line and the Kwun Tong line extension were signed by the Hong Kong government and MTR Corporation on 18 May 2011. In August 2012, drilling and blasting work began for constructing the Nam Fung Tunnel, between Admiralty and Ocean Park stations. The main contractor was Leighton Contractors with John Holland Group sharing part of the works.
  On 9 December 2013, structural work for Ocean Park station was completed. The first 3-car trainset arrived at MTR Siu Ho Wan Depot on 19 February 2014. The project was 78% complete by late September 2014, and Nam Fung Tunnel was broken through on 17 October. In 2015, trial runs began between Wong Chuk Hang and South Horizons stations. 84% of construction work was completed by the end of February 2015. Work in Lei Tung station was prolonged by geological problems, but the MTR claimed it would not postpone the line opening.
