10 things to know about the Singapore MRT

The MRT looks like the tidiest metro on earth: clean platforms, air conditioning everywhere, trains that actually arrive when the app says they will. Underneath that tidiness is a network with some genuinely strange engineering and history, most of which never makes it onto a tourist map. Here are ten things worth knowing before you play dailymetro.live/singapore.

None of this is trivia-night filler. It is the kind of detail that explains why a station looks the way it does, or why one platform sits so much deeper than the next.

1. It started as five stations on one line

The MRT opened on 7 November 1987 with a first stretch of about 6 km and five stations on what is now the North-South Line. Everything else, the East-West, North East, Circle, Downtown and Thomson-East Coast lines, was built afterwards, in stages, over the following four decades.

2. Some stations double as bomb shelters

A number of the deeper underground stations were built as civil defence shelters: hardened concrete station boxes and reinforced steel blast doors, ready to seal the platform off from the rest of the tunnel in an emergency. Commuters walk past the machinery every day without noticing it.

3. The escalators are deliberately fast

Most of the network's heavy-duty escalators run at 0.75 m/s, about 50% faster than a conventional escalator. It is not an accident: Singapore's stations are unusually deep for a tropical, low-lying city, and slow escalators would mean long queues at rush hour.

4. The deepest station is a squeeze

Bencoolen, on the Downtown Line, sits 43 metres below street level, the deepest station on the network. It was also built on an extremely tight footprint, just 22 metres wide and 140 metres long, which is why the concourse curves like a canyon and the lift glass is tinted maroon, a nod to descending toward the earth's core. It will not hold the depth record forever: the future Cross Island Line platforms at Pasir Ris are planned at 47 metres.

5. One station's roof is a swimming pool

Bras Basah station, on the Circle Line, was built 35 metres down but designed so a shallow reflecting pool sits directly over the concourse, doubling as the station's roof and its skylight. Daylight filters down through the water by day, cutting the need for artificial lighting. The design won Best Transport Building at the 2009 World Architecture Festival. The same station also has the network's longest single escalator, 41 metres end to end.

6. Art in Transit is Singapore's largest public art programme

Launched with the opening of the North East Line in 2003, Art in Transit commissions artists to build work directly into a station's architecture rather than hang it on a wall afterwards. Over 300 pieces now sit across roughly 80 stations, making it, by the operator's own description, Singapore's biggest public art programme, and one most riders walk past without registering as art at all.

7. Dhoby Ghaut is the network's biggest station, and its name is a piece of local history

Dhoby Ghaut takes its name from Hindi: dhobi for washerman, ghat for the steps along a river, a reference to the open-air laundry that once worked the stream running through the area. It became Singapore's first triple-line interchange when the Circle Line platforms opened in 2010, joining the North-South and North East lines, and it spans five underground levels, the largest station on the network. Getting between the North East and North-South platforms means a 55-metre travelator, the first of its kind on the MRT.

8. Some stations exist mostly to serve a boat

Marina South Pier, the southern terminus of the North-South Line, opened in 2014 chiefly to connect commuters to the Marina South Pier ferry terminal and the Marina Bay Cruise Centre. The surrounding land is still largely undeveloped, and the operator recorded only 2,178 boardings a day there in June 2024, one of the quietest stations in the system.

9. Lines are named for geography, not colours or numbers

North-South, East-West, North East, Circle, Downtown, Thomson-East Coast: every MRT line describes where it goes rather than what colour it is drawn in, unlike most of the metros that inspired it. As of mid-2026 the six lines together cover about 246.6 km and 146 stations, making the MRT one of the largest fully urban rapid transit networks in Southeast Asia.

10. one-north is written in lowercase on purpose

one-north, on the Circle Line, is the only station on the network whose official name starts with a lowercase letter. It follows the branding of the one-north business and research district above it rather than the MRT's usual capitalised station names, a small typographic oddity that trips up anyone typing it into a search box.
