TheSouth Island line (West) is a proposed extension of the Hong KongMTRmetro system. The new line would serve the southwestern coast ofHong Kong Island, betweenShek Tong Tsui andWong Chuk Hang. Plans for the South Island line (West) are mentioned and revised in the government'sRailway Development Strategy 2014 (RDS-2014) report.[1] and construction was planned to begin in 2021–2026 in the report.[1]: 61
Like the existingSouth Island line, this line would connect theSouthern District to the rest of the MTR network.

The idea of connecting theSouthern District of Hong Kong was proposed as early as the 1980s. The Government proposed the southward extension of then-plannedEast Kowloon Line toAberdeen fromSheung Wan in 1989.[2] Four years later the transport authorities published a consultative document that proposed the construction of two South Island lines interchanging atTin Wan: vertical running fromAdmiralty toLei Tung via Tin Wan andAp Lei Chau, and horizontal fromTelegraph Bay (nowCyberport) toOcean Park viaWah Fu Estate,Wah Kwai, Tin Wan, Aberdeen, and Wong Chuk Hang. It was also deemed there is no urgency for the project considering the road system is considered to be sufficient.[3] A same conclusion was reached in 1999 study except moving the proposed northern terminus to Sheung Wan station.[4]
In the Railway Development Strategy (RDS) 2000, South Island line was included in the long-term development list, but was abandoned to fully consider the alignment of the line. Despite multiple pledge to implement the scheme, including in 2007 announcing the construction to start in 2011,[5] in 2013 to start in 2015,[6] and in 2014 to start in 2021,[7] the project is still in planning stage as of 2023, when theTransport and Logistics Bureau confirmed the commission of the line would depend on the reconstruction of Wah Fu Estate in 2027.[8]

The following is a list of the stations on the South Island line (West), including HKU, QMH, Cyberport, Wah Fu, Wah Kwai, Tin Wan, Aberdeen and Wong Chuk Hang.
