Northern Link (MTR)

The Northern Link is a proposed rapid transit line of the MTR system of Hong Kong which would connect the Tuen Ma line and the Lok Ma Chau Spur Line of the East Rail line. The link would also serve as a connection to the border checkpoint to mainland China for passengers to and from the western New Territories. The Northern Link would start at Kam Sheung Road and end at Kwu Tung, and would be constructed either as a direct shuttle or with intermediate stations.

Other benefits for constructing this project are significantly shorter journey times for certain trips (for example, the Yuen Long to Fanling route would be reduced in length from 20 stations to 5), significantly reducing costs for these trips, as well as relieving the large number of passengers using the East Rail line by diverting some passengers to the Tuen Ma line.

According to the Railway Development Strategy 2014, a shuttle service between Kam Sheung Road station and Kwu Tung station spanning 10.7 km is expected to begin construction in 2018 and be inaugurated in 2023.

The initial line is expected to cost HK$62 billion in December 2015 prices, with an average of HK$500 million/km.

Phases
The Northern Link (NOL) project is expected to consist of two phases.

Phase 1
Phase 1 consists of the construction and completion of Kwu Tung station that will initially serve the East Rail line after its opening, then later the Northern Link after the completion of Phase 2. It had been partially built by KCR Corporation during the construction of the Lok Ma Chau Spur Line. Construction of Kwu Tung station was approved by the government in 2022 is scheduled to commence in 2023 with completion due in 2027.

It is expected to cost HK$3.5 billion in December 2015 prices.

Phase 2
Phase 2 consists of the building of the Northern Link main line tracks from Kam Sheung Road station to Kwu Tung station. It also includes the construction of 3 new stations (Au Tau, Ngau Tam Mei and San Tin) along with the expansion of Kam Sheung Road station to accommodate the new tracks and platforms. Planning and designing began in 2021. Construction of the mainline is planned to begin in 2025 and be completed in 2034.

It is expected to cost HK$58.5 billion in December 2015 prices.

Land hoarding
In July 2021, Liber Research Community found that developers had begun to hoard land alongside the Northern Link line, buying at least 80 hectares of land near the line.
