of Wah Fu and Ap Lei Chau in Southern District and the CBD of Hong Kong. This was the first project within the MTR network that serves the Southern District. Three proposals were previously submitted, each addressing the drawbacks of the prior plan. The plans were turned down by the government in favour of constructing highways in late March 2004. The MTRC's fourth proposal was given in February 2005. This consisted of an westward extension of the Island line (referred to as West Island line in early planning) and the South Island line (East), which would be connected to the South Island line (West) at HKU station and Wong Chuk Hang station, respectively. The South Island line (East), currently simply referred to as the South Island line, opened on 28 December 2016. Plans for the South Island Line (West) were mentioned and revised in the 2014 governmental railway strategy report and an "implementation window" of 2022 to 2026 was identified. A proposal for South Island line (West) was submitted by MTR to the Government of Hong Kong in December 2020. As of 2022, there is no schedule for construction. North Island line This would link the Tung Chung line (Hong Kong station) and the Tseung Kwan O line (at North Point). There is currently no schedule for construction. East Kowloon line The original scheme of the East Kowloon line would connect Diamond Hill station via Hung Hom station to Sheung Wan station. It was refined and merged into what is today known as the East West Corridor without crossing the harbour to Sheung Wan. In 2014, another railway scheme of the same name was unveiled by the government which would provide metro service in the opposite direction to Po Lam station, HKUST Station, via Sau Mau Ping. The 2014 railway development strategy recommended the new line should begin construction in 2019 and be finished in 2025. However, construction has yet to begin and there is no schedule for construction. Tung Chung to Tai O Light Rail System On December of 2017, CEDD hired a consultant to study the possibility of a light rail link between Tung Chung station and Tai O Fishing Village on Lantau Island. The light rail will go around Tung Chung, the airport and the Hong Kong–Zhuhai–Macau Bridge and will take only 15 minutes to make the trip, opposed to the 45 minute bus ride along a
