Singapore's Mass Rapid Transit (MRT) is one of the most efficient urban rail systems in the world. It is clean, air-conditioned, punctual (disruptions notwithstanding), and covers virtually the entire island. For a visitor, it is the most rational way to move around Singapore for the vast majority of journeys — faster than taxis in traffic, dramatically cheaper, and reliable enough to plan around. This guide covers everything you need to use it confidently from day one.
Singapore's MRT currently operates six lines, identifiable by colour on the network map. You don't need to memorise all of them — the journey planner on the MyTransport SG app or Google Maps routes you automatically — but knowing the primary lines helps when reading station signage and choosing the right entrance.
North-South Line (NSL, Red): Runs from Jurong East in the west through the city centre (Orchard, City Hall, Raffles Place) to Marina Bay and north to Woodlands and Sembawang. This is the primary line for most tourist journeys — Orchard, City Hall, and Raffles Place are all on the NSL.
East-West Line (EWL, Green): Runs from Tuas Link in the far west through the city (Bugis, City Hall, Raffles Place) to Pasir Ris and Changi Airport in the east. Changi Airport station (CG) is a branch off the EWL. The EWL serves Tiong Bahru (EW17), Queenstown (EW19), and Bugis (EW12).
North East Line (NEL, Purple): Runs from HarbourFront in the south through Little India, Chinatown (NE4), and Dhoby Ghaut to Punggol in the northeast. Serves the Chinatown, Little India, and Farrer Park areas.
Circle Line (CCL, Orange): A circular line (with a branch) that connects the outer reaches of the network. Serves the Botanic Gardens (CC19/DT9), Marina Bay (CE2), and the Stadium and Sports Hub area (CC7).
Downtown Line (DTL, Blue): The most recent major line addition, running from Bukit Panjang through the city centre (Bugis DT14, Chinatown DT19, Bayfront DT16/CE1) to Expo and Changi Airport. Serves many neighbourhoods that were previously underserved by rail.
Thomson-East Coast Line (TEL, Brown): Singapore's newest line, still being extended. Currently serves Woodlands, Caldecott, Stevens, and the East Coast through Orchard (TE14) and Maxwell (TE18) stations. Fully operational sections offer excellent connectivity through the city.
The EZ-Link card is Singapore's contactless transit payment card. It replaces single-journey tickets for all regular travel and is the non-negotiable starting point for any Singapore visit. Get one at the Passenger Service Centre at Changi Airport's arrival hall before leaving the terminal — it is the most convenient point of purchase, staffed whenever flights are arriving, and eliminates the need to find a machine on your first day.
The card costs SGD 10 (which includes SGD 5 of stored value and a SGD 5 non-refundable card fee). Load additional value at any ticketing machine inside any MRT station or at 7-Eleven stores. The minimum reload is SGD 10.
To use: tap the card on the reader at the fare gate when entering the station and tap again when exiting. The system calculates your fare based on distance and deducts it automatically. Single journeys range from SGD 0.92 to SGD 2.17 depending on distance. A typical tourist journey across the city costs SGD 1.20–1.80.
At the end of your trip, refund the remaining value (minus a SGD 1 administrative fee) at any TransitLink Ticket Office inside MRT stations. Only worth doing if you have more than SGD 5 remaining — otherwise, keep the card for future Singapore visits.
The MRT connection from Changi Airport to the city is straightforward and one of the best airport rail connections in Asia. The Airport MRT station (CG2) is directly below Terminals 2 and 3 and connects to Terminal 1 via the free Skytrain. Terminal 4 requires a free shuttle bus to Terminal 2 before joining the MRT.
To Orchard Road (shopping, many hotels): Take the East-West Line (green) from Changi Airport toward Tuas Link. Change at Tanah Merah (CG/EW4) to the main East-West Line. Continue to City Hall (EW13/NS25) or Raffles Place (EW14/NS26) and change to the North-South Line northbound to Orchard (NS22). Total journey: approximately 45–55 minutes. Fare: approximately SGD 1.70–2.00.
To Marina Bay / Marina Bay Sands: East-West Line from Changi to City Hall, then change to the Circle Line or walk. Alternative: Downtown Line from Expo (DT35, one stop from Changi Airport via the DTL airport branch) to Bayfront (DT16/CE1). Total journey: approximately 35–45 minutes via the Downtown Line route.
To Chinatown: East-West Line to Outram Park (EW16/NE3), change to the North East Line, one stop to Chinatown (NE4). Or Downtown Line from Expo to Chinatown (DT19). Approximately 40 minutes.
City Hall (EW13/NS25): The centre of Singapore's transit network. The Padang, St Andrew's Cathedral, the Esplanade, and Marina Bay are all within walking distance. Interchange for the North-South and East-West lines.
Raffles Place (EW14/NS26): The financial district. The Singapore River, Boat Quay, and Clarke Quay are a short walk. Good starting point for river walks.
Bayfront (CE1/DT16): Gardens by the Bay, Marina Bay Sands, and the ArtScience Museum are directly accessible from this station. Central to the Marina Bay tourist circuit.
Chinatown (NE4/DT19): Direct access to Chinatown. Maxwell Food Centre is a five-minute walk via the exit toward Neil Road.
Orchard (NS22/TE14): Heart of the Orchard Road shopping belt. Multiple exits connect to different shopping malls.
Little India (NE7/DT12): Serangoon Road, Tekka Market, and the Sri Veeramakaliamman Temple are immediately accessible.
Bugis (EW12/DT14): Gateway to Kampong Glam, Arab Street, Haji Lane, and the Sultan Mosque. Ten-minute walk to most of the quarter.
Botanic Gardens (CC19/DT9): Direct station access to the Singapore Botanic Gardens. The main Tanglin Gate entrance is immediately adjacent.
Check the direction before boarding. Platforms are directional — "towards Jurong East" and "towards Pasir Ris" for the East-West Line, for example. The display boards show the next two or three stations in each direction. If you board the wrong direction, get off at the next station and cross the platform.
Stand on the left of escalators, walk on the right. This is a firm social convention in Singapore MRT stations. Ignoring it during peak hours will earn you looks.
Give up priority seats. Orange-marked priority seats are for the elderly, pregnant women, passengers with disabilities, and those with young children. You'll be expected to give up a standard seat too if someone clearly needs it — this is an unwritten rule Singaporeans take seriously.
No eating, no drinking. The SGD 500 fine for consuming food or drink in MRT stations or on trains is real and enforced. Water bottles are grey-area but technically covered. Don't risk it.
The MRT stops running around midnight. Last train times vary by line and direction but generally fall between 11:30 PM and 12:30 AM. The MRT website publishes the last train schedule for each station. For late-night travel, Grab (Singapore's ride-hailing app) is the practical alternative.
Night Owl buses: Selected bus services run through the night on weekends, covering major routes after the MRT closes. These are slower but cheaper than Grab for non-urgent late-night journeys.
Google Maps works well for Singapore MRT journey planning — it is accurate on routes, transfers, and journey times, and it incorporates real-time service information. The MyTransport SG app (official, from the Land Transport Authority) provides additional features including bus arrival times and service disruption alerts. Either works for basic navigation.
For the first few days, screenshot your planned route at the hotel before heading out — data can be slow in crowded station concourses. After three or four MRT journeys, the network becomes intuitive for the main tourist areas.
