Future projects of the MTR

Several future projects on the MTR have been put forward by the MTR Corporation to the Hong Kong Government. Some of these are still in planning stage.

With the rail merger with the Kowloon-Canton Railway Corporation in 2007, the combined network increased to 211.6 kilometres (131.5 mi) and 84 stations. Committed and future railway projects have increased the network to over 270 kilometres (170 mi) and 98 stations today while the rest of the projects may further increase it to over 540 kilometres (340 mi).

The Northern Link is a 26 km rapid transit line that once completed, will create a new railway corridor between the Tuen Ma line and the East Rail line in northern New Territories. This project consists of two phases; the first with the opening of Kwu Tung station and the second involves the construction of the Northern Link main line, 3 new stations and the expansion of the existing Kam Sheung Road station. The termini of the line will be Kwu Tung station and Kam Sheung Road station. The completion of both phases was estimated to cost HK$62 billion in 2015. Kwu Tung station will be commissioned in 2027, while construction of the Northern Link is scheduled to start in 2025 and end in 2034. The area surrounding the station will be developed into a New Development Area.

In the 2022 Chief Executive's policy address, a new railway line would be built to connect Kam Tin with Kowloon Tong through Kwai Chung to relieve capacity from the Tuen Ma line. It would act as an extension of the Northern Link and interchange at Kowloon Tong station.

The deputy chairman of the Legco subcommittee on railway affairs, Gary Zhang, added that the Tuen Ma line alone could not provide the capacity needed for commuters travelling from the planned Northern Metropolis to Kowloon and Hong Kong Island.

The Tung Chung Line Extension project comprises two main components. The first involves a 1.3 km westward extension from the existing western terminus, Tung Chung Station, to establish a new terminus, Tung Chung West Station. Additionally, an infill station, Tung Chung East Station, will be constructed between the existing Tung Chung and proposed Oyster Bay stations.

In January 2023, Chief Executive John Lee and the Executive Council approved the Tung Chung Line Extension project. Construction commenced in 2023, and the estimated cost of the two new stations, Tung Chung East and Tung Chung West, is HK$24.2 billion. The contract for the extension was awarded to British engineering companies Arup and Atkins. This extension is expected to be complete by 2029.

Oyster Bay station, previously Siu Ho Wan station, is a planned infill station that will be situated in between Sunny Bay station and the future Tung Chung East station. It is expected to open with the Siu Ho Wan Depot Topside Property Development Package 1. The station will be part of the Tung Chung line. It is expected to open in 2030.
