I moved to Hong Kong partly because of the MTR. Not entirely, obviously — the food, the harbour, the energy, the perverse pleasure of watching the city function at a density most cities would find impossible. But the train system was a significant factor in the calculation. Coming from London, where the Tube is ancient, frequently unreliable, and designed to crush whatever enthusiasm for urban living you might have arrived with, Hong Kong's MTR was a revelation. Clean, frequent, on time, cheap, and covering the city with a logic that makes sense even to first-timers.
Ten-plus years later, I still think this. And the system continues to expand in ways that matter, particularly for anyone thinking about where to live, how long their commute will be, and which neighbourhoods are quietly becoming more viable for the kind of life they want. This is that article: what's been built, what's being built, and what it means for your commute and your property decisions.

The Tuen Ma Line — What It Changed, and Why You Should Know It
Tuen Ma Line 屯馬線
The Tuen Ma Line is the most recently completed major MTR project and still probably the most underappreciated by people who live on Hong Kong Island or in Kowloon. At 56.4 kilometres with 27 stations, it runs from Wu Kai Sha in Ma On Shan all the way through the city to Tuen Mun — merging what were previously the separate Ma On Shan Rail and West Rail into a single continuous line. The line is genuinely significant for New Territories residents because it provides a single-train connection that previously required changing lines or taking buses. Shatin, Tai Wai, Diamond Hill, Sung Wong Toi, Kai Tak, Ho Man Tin, Hung Hom, Whampoa — stations that now connect seamlessly to Kowloon and beyond. If you haven't ridden the full line from end to end, it's a genuinely interesting urban journey — you move through residential New Territories, new development areas, reclaimed land at Kai Tak, and back through classic Kowloon. The city's variety in 90 minutes and HKD 10.
The Kai Tak station deserves particular mention. Built on the old Kai Tak airport site — which you will remember if you're old enough, or know by reputation if you're not, as the airport with the runway that appeared to end in Victoria Harbour — the new development district around the station is one of the most interesting areas of emerging urban life in Hong Kong. The Kai Tak Sports Park, a major new stadium complex, has opened here. Residential and commercial development is continuing. Kai Tak is, essentially, Hong Kong's biggest new neighbourhood, and the Tuen Ma Line is what makes it viable. If you're considering where to live in Kowloon and want somewhere that's going to appreciate in urban value over the next decade, Kai Tak is the obvious answer.
Northern Metropolis — The Decade-Defining Project
Northern Metropolis Development Strategy 北部都會區
The Northern Metropolis is the largest planning and infrastructure initiative Hong Kong has undertaken since the New Towns programme of the 1970s and 80s. Announced in the 2021 Policy Address, it covers a swathe of northern New Territories — broadly the areas bordering Shenzhen, from Hung Shui Kiu in the west through Kwu Tung, San Tin, and east to Fanling and beyond. The strategic logic is to create a major new urban zone that leverages the proximity to Shenzhen and the opportunities created by Greater Bay Area integration. The target is to accommodate approximately 900,000 additional residents in the northern NT and to house a significant portion of Hong Kong's innovation and technology sector, which is being actively directed northward. The transport components include the Northern Link (an MTR extension that will connect Kwu Tung and San Tin to the existing network), enhanced cross-border rail links, and new express connections to Shenzhen.
Let me be honest about what this means in practical terms. The Northern Metropolis is a long-term project. Its full realisation is years away, and large infrastructure programmes in Hong Kong, as everywhere, tend to run behind initial timelines. If you're making a property decision based on what Northern Metropolis connectivity will look like in 2035, you are making a speculative bet that requires patience and tolerance for construction-adjacent living in the medium term.
That said, the direction is clear and the government commitment is genuine. The northern NT is going to become significantly more connected, more populated, and more economically active over the next decade. Property prices in areas like Hung Shui Kiu and Kwu Tung already reflect some of this anticipation. The workers in Hong Kong's expanding innovation and technology sector — which is being explicitly directed toward the Northern Metropolis zone — will need somewhere to live. This is where they'll live.
Northern Metropolis Key Rail Projects
| Project | What It Does | Target Completion | Affected Areas |
|---|---|---|---|
| Northern Link 北環線 | New MTR line connecting Kwu Tung to Kam Sheung Road (existing Tuen Ma Line) | ~2034 | Kwu Tung, San Tin, Robin's Nest area |
| Hung Shui Kiu Station | New station on existing Tuen Ma Line to serve HSK new town | ~2027-2030 | Hung Shui Kiu / Ha Tsuen |
| San Tin Technopole Rail | Rail access for the innovation cluster at San Tin | Under planning | San Tin, Lok Ma Chau border area |
| Enhanced Cross-Border Links | More frequent and direct cross-border rail to Shenzhen | Phased | Lo Wu, Lok Ma Chau, new connection points |
Tung Chung Line Extension — Lantau's Growing Population
Tung Chung Line Extension 東涌線延線
The Tung Chung Line Extension is a more contained project than the Northern Metropolis but directly relevant to anyone living in or considering living in Tung Chung. The extension adds two new stations — Tung Chung East and Tung Chung West — to the existing Tung Chung Line (which currently runs from Tung Chung to Hong Kong station in Central). Tung Chung New Town has expanded significantly as a residential district over the past decade, and the original single station was increasingly inadequate for the population it was serving. The East station will serve the eastern expansion of the new town; the West station serves the growing western residential areas. Anticipated completion is in the late 2020s, though specific dates have shifted during construction.

What MTR Expansion Means for Property and Lifestyle
The relationship between MTR access and property values in Hong Kong is one of the most well-documented in the world. New stations are a reliable predictor of rising property prices in the surrounding areas — the "MTR premium" is real and measurable. Areas with poor rail connectivity but good road access (parts of the New Territories, Sai Kung, some Island areas) command a significant discount to equivalent quality housing with MTR access. As new stations open, this discount narrows.
Practically, here's the analysis by area:
Where Rail Expansion Will Affect Your Commute and Property
- Kai Tak: Already served by Tuen Ma Line (Kai Tak station). The new development is building out rapidly. Sports Park anchor (stadium) is open. This is the most established of the "new" areas.
- Tung Chung: Improving local connectivity with the East and West stations. The airport-adjacent location and improving connectivity are making this a more attractive residential option for airport-adjacent workers and value-conscious buyers.
- Hung Shui Kiu / Ha Tsuen: Approved for a new Tuen Ma Line station and future Northern Link access. Currently one of the more affordable large-flat markets in Hong Kong. The new town development is ongoing.
- Kwu Tung / San Tin: Northern Metropolis core. New rail coming but timeline is long. Buy here as a very long-term investment only.
- Existing Tuen Ma Line areas (Shatin, Tai Wai, Fo Tan): Already fully served and well-priced relative to Hong Kong Island equivalents. These remain good value-for-size options for working families who need space.
Commute Impact Summary — Who Benefits Now and Who Benefits Later
If you're making a housing decision based on commute time right now, here's the honest picture:
Already fully served: Tuen Ma Line is running and reliable. If you work in Kowloon or need to connect to the East Rail Line or the Tung Chung Line, the New Territories communities along the Tuen Ma Line are now properly connected. Shatin to Central is approximately 40-45 minutes. Tai Wai to Admiralty is around 35 minutes.
Being served now: Tung Chung local connectivity is improving as the East and West stations come online. This affects existing Tung Chung residents positively but the route to Central (Tung Chung Line to Hong Kong station) remains the same.
Future benefit, medium-term (2027-2030): Hung Shui Kiu area residents will gain a rail station on the Tuen Ma Line, significantly improving access to Kowloon and East Rail connections. Currently these residents rely on buses.
Future benefit, long-term (2030+): Northern Link and Northern Metropolis railway projects will reshape the northern NT. This is a genuine 10-year horizon. Invest accordingly.
