Choi Hung MTR station on the Kwun Tong Line
Hong Kong’s Mass Transit Railway, universally known as the MTR, is the single most important piece of infrastructure in the city. It carries over five million passengers every weekday across 10 heavy rail lines, 99 stations, and 245.3 kilometres of track. For expats arriving in Hong Kong, understanding the MTR is not optional: it is the fastest, most reliable, and most cost-effective way to get around.
Unlike subway systems in many Western cities, the MTR is clean, air-conditioned, punctual to the minute, and covers virtually every populated corner of the territory. Trains run from approximately 6:00 in the morning until 1:00 at night, with frequencies as short as two minutes during rush hour. The system is operated by the MTR Corporation, a publicly listed company in which the Hong Kong government holds a majority stake.
Whether you are commuting to Central for work, heading to the airport, or exploring the New Territories on a weekend, the MTR will almost certainly be part of your journey. This guide covers everything a new expat needs to know: the network layout, how to pay, what the fares look like, and the unwritten rules that keep the system running smoothly.

The MTR Network at a Glance
The MTR network consists of 10 heavy rail lines that together form one of the densest urban rail systems in the world. Each line is colour-coded, and interchange stations allow passengers to transfer between lines without leaving the paid zone.
The completion of the East Rail Line cross-harbour extension in May 2022 connected the New Territories directly to Admiralty on Hong Kong Island for the first time, eliminating a transfer that previously frustrated East Rail commuters for decades. The Tuen Ma Line, fully operational since June 2021, created a continuous east-west rail corridor across the New Territories and Kowloon.
Here is an overview of all 10 lines:
| Line | Colour | Key Stations | Where It Goes |
|---|---|---|---|
| Island Line | Blue | Kennedy Town, Central, Admiralty, Causeway Bay, Chai Wan | Along the north shore of Hong Kong Island |
| Tsuen Wan Line | Red | Central, Tsim Sha Tsui, Mong Kok, Lai King, Tsuen Wan | Cross-harbour from Central to western NT |
| Kwun Tong Line | Green | Whampoa, Mong Kok, Kowloon Bay, Kwun Tong, Tiu Keng Leng | Eastern Kowloon industrial and residential belt |
| Tseung Kwan O Line | Purple | North Point, Quarry Bay, LOHAS Park, Po Lam | Eastern harbour crossing into Tseung Kwan O |
| East Rail Line | Light Blue | Admiralty, Hung Hom, Sha Tin, University, Lo Wu/Lok Ma Chau | Cross-harbour to NT, Shenzhen border |
| Tuen Ma Line | Brown | Wu Kai Sha, Tai Wai, Hung Hom, Tsim Sha Tsui, Tuen Mun | East-west across NT and Kowloon |
| South Island Line | Yellow-green | Admiralty, Ocean Park, Wong Chuk Hang, South Horizons | Southern side of Hong Kong Island |
| Disneyland Resort Line | Pink | Sunny Bay, Disneyland Resort | Shuttle from Tung Chung Line |
| Tung Chung Line | Orange | Hong Kong, Kowloon, Tsing Yi, Tung Chung | West Kowloon to Lantau Island |
| Airport Express | Teal | Hong Kong, Kowloon, Tsing Yi, Airport | Direct express to HKIA |
Key interchange stations to remember: Admiralty (4 lines), Central/Hong Kong (3 lines, connected by underground walkway), Kowloon Tong (East Rail + Kwun Tong), Mei Foo (Tsuen Wan + Tuen Ma), and Nam Cheong (Tung Chung + Tuen Ma). Learning these interchange hubs makes navigating the entire network significantly easier.

Getting an Octopus Card

The Octopus Card is a rechargeable contactless smart card that works on the MTR, buses, ferries, trams, minibuses, and at thousands of retail outlets across Hong Kong. It is, for practical purposes, essential. While single journey tickets exist, they cost more per trip and require queuing at ticket machines each time.
Standard Octopus Card: Available at any MTR Customer Service Centre. The card costs HKD 50 as a refundable deposit. You load value on top of this deposit: a minimum initial top-up of HKD 50 is typical, so you will pay HKD 100 at the counter and walk away with HKD 50 of stored value. If you return the card within 90 days of issue, a HKD 11 handling fee is deducted from the deposit refund.
Tourist Octopus Card: Available at the Airport Express Customer Service Centre and selected MTR stations. It costs HKD 39 with no refundable deposit. It functions identically to a standard card but is designed for short-term visitors.
Digital Octopus: Both Apple Pay and Google Pay support Octopus integration. You can add a digital Octopus to your phone’s wallet and tap in and out using your device. This is increasingly popular among younger residents and tech-savvy expats who prefer not to carry a physical card.
Topping up: Add value at any MTR station (ticket machines accept cash and EPS), at 7-Eleven and Circle K convenience stores, or via the Octopus app linked to a bank account or credit card. The maximum stored value on a standard card is HKD 3,000.
The Octopus Card also supports an automatic negative value feature: if your remaining balance is insufficient for a fare but above negative HKD 50, the gate will still let you through. You must top up before your next journey.
Fares and Tickets
MTR fares are distance-based. The minimum adult fare is HKD 3.50 (for a short one-station hop) and the maximum is HKD 51.00 (for the longest possible journey, such as Tung Chung to Lo Wu). The full fare table is published on the MTR website.
Octopus vs Single Journey Ticket: Octopus fares are consistently cheaper than single journey ticket fares for the same route. The discount ranges from a few cents to several dollars depending on the distance. There is no reason to use single journey tickets if you have an Octopus Card.
Common route fares (Octopus, adult):
| Route | Fare (HKD) |
|---|---|
| Central to Tsim Sha Tsui | 13.00 |
| Central to Causeway Bay | 5.10 |
| Admiralty to Sha Tin | 13.80 |
| Mong Kok to Kowloon Bay | 5.10 |
| Tung Chung to Central | 25.00 |
| Hung Hom to Lo Wu (Shenzhen border) | 41.30 |
Concessionary fares: Children aged 3 to 11, senior citizens aged 65 and above, and eligible students pay approximately half the adult fare. Children under 3 travel free.
Tourist Day Pass: Priced at HKD 75 for adults and HKD 35 for children, this pass gives unlimited MTR travel for 24 consecutive hours from first use. It covers all lines except Airport Express, East Rail Line First Class, and trips to Lo Wu and Lok Ma Chau stations.
City Saver: The City Saver is designed for regular commuters. It costs HKD 460 for 40 single journeys, valid for 40 days from first use. This works out to HKD 11.50 per trip, which is excellent value for commuters travelling medium distances.
Monthly Pass: The MTR Monthly Pass Extra provides unlimited rides between designated station zones, plus a 25% discount on connecting journeys outside the zone. Pricing varies by zone and is worth calculating against your actual commuting pattern.
How to Ride the MTR: A Step-by-Step for First-Timers
Step 1: Enter the station. Look for the MTR logo (a stylised red and white symbol). Most stations have multiple entrances labelled A, B, C, D, each serving different street exits. Choose the entrance closest to your destination for a shorter walk on arrival.
Step 2: Tap in. Hold your Octopus Card or phone flat against the yellow sensor on the fare gate. The gate opens, and the screen displays your remaining balance. Walk through promptly.
Step 3: Find your platform. Follow the overhead signs. Directional signs are in English and Chinese throughout. Island-bound platforms and terminal station names are displayed clearly. If transferring between lines, follow the interchange signs (colour-coded arrows matching the line colours).
Step 4: Board the train. Platform screen doors separate the platform from the track at most stations. These doors open automatically when the train arrives. Queue on either side of the doors and let passengers exit before boarding. This is not just etiquette: it is actively enforced by passenger flow.
Step 5: Ride. Electronic displays above the doors show the current station and upcoming stops in English and Chinese. Audio announcements are made in Cantonese, Mandarin, and English. The MTR app also tracks your position in real time.
Step 6: Tap out. At your destination station, tap your Octopus Card at the exit gate. The fare is deducted automatically, and your new balance is displayed. Follow the exit letter signs (A, B, C, D) to reach the correct street-level exit.
Peak hours run from approximately 8:00 to 9:30 in the morning and 6:00 to 7:30 in the evening on weekdays. Trains during peak are crowded, particularly on the Tsuen Wan Line (Central to Mong Kok corridor) and the East Rail Line. Off-peak travel is dramatically more comfortable.
Train frequency: During peak hours, trains arrive every 2 to 3 minutes on the busiest lines. Off-peak frequency drops to 4 to 8 minutes. Late-night services run at approximately 10 to 12 minute intervals.
The Airport Express

The Airport Express is a premium service connecting Hong Kong International Airport to the city centre in approximately 24 minutes. It is the fastest and most convenient way to travel between the airport and urban Hong Kong.
Fares:
| From | To Airport (Single Ticket) | To Airport (Octopus) |
|---|---|---|
| Hong Kong Station | HKD 130 | HKD 120 |
| Kowloon Station | HKD 115 | HKD 105 |
| Tsing Yi Station | HKD 75 | HKD 65 |
In-Town Check-In: One of the Airport Express’s most useful features is the ability to check in your luggage and receive your boarding pass at Hong Kong Station or Kowloon Station. Airlines including Cathay Pacific, Hong Kong Airlines, and several others support this service. Check-in counters are open from one day before departure until 90 minutes before your flight. You can then travel to the airport hands-free.
Free shuttle buses: The Airport Express operates complimentary shuttle bus services from Hong Kong Station and Kowloon Station to major hotels and transport hubs in the surrounding areas. Routes and schedules are posted at the stations and on the MTR website.
Round trip and group discounts: A same-day return ticket costs the same as a single, and group tickets for two, three, or four passengers offer significant per-person savings. Check the ticket machines or customer service counters for current group pricing.
Light Rail and MTR Buses
The MTR system extends beyond the heavy rail network. Two additional services are relevant if you live in or visit the northwest New Territories.
Light Rail: The Light Rail operates 12 routes across 68 stops in the Tuen Mun, Yuen Long, and Tin Shui Wai areas. Unlike the heavy rail MTR, Light Rail vehicles run at street level and share road space with traffic in some sections. Fares are distance-based and payable by Octopus Card. The Light Rail functions as the primary public transport network for residents in these districts, feeding into the Tuen Ma Line and West Rail corridor.
MTR Buses: The MTR Corporation operates feeder bus routes that connect residential areas to nearby MTR and Light Rail stations. These are standard bus services (not rail), and fares are typically HKD 4 to HKD 8. They are particularly useful in Tuen Mun, Yuen Long, and areas around Tseung Kwan O.
If you are considering renting a flat in the northwest New Territories, the Light Rail network and MTR bus routes should factor into your transport assessment alongside the main MTR lines.
Rules and Etiquette

The MTR is remarkably orderly, and much of that order comes from both formal rules and informal social norms. Violating either will draw attention.
No eating or drinking. This is a legal prohibition, not a suggestion. Consuming any food or beverage (including water) inside the paid area of any MTR station or on any train is an offence under the MTR By-laws. The fine is HKD 2,000. Enforcement is real: MTR staff and plainclothes inspectors do issue fines.
No smoking. Smoking is prohibited throughout the entire MTR system, including station entrances and concourses.
Priority seats. Every carriage has designated priority seats (marked in a different colour) for elderly passengers, pregnant women, and people with disabilities. You may sit in them if they are empty, but you are expected to give them up immediately when someone who needs them boards.
Escalator etiquette. Stand on the right, walk on the left. This is one of Hong Kong’s most consistent social norms and applies to every escalator in every MTR station. Blocking the left side of an escalator during rush hour will generate visible frustration from commuters behind you.
Queuing. At platform screen doors, passengers form orderly queues on both sides of the door markings. Let exiting passengers off first, then board. Pushing or cutting the queue is rare and poorly received.
Backpacks and luggage. During peak hours, consider wearing your backpack on your front or holding it by your side. Large suitcases are permitted but can be difficult to manoeuvre during rush hour. The Airport Express is designed for luggage; regular MTR lines are not.
Phone calls. There is no formal prohibition on phone calls, but most regular commuters avoid loud conversations. Extended or loud phone calls on a quiet carriage will draw stares.
Useful Apps and Tips for Expat Commuters
MTR Mobile App: The official MTR Mobile app is free and available in English. It includes a journey planner with real-time estimated arrival, fare calculator, station facility maps, and service disruption alerts. It is the single most useful transport app for MTR travel.
Citymapper and Google Maps: Both apps integrate MTR data and provide multimodal journey planning (MTR + bus + walking). Citymapper is particularly good at showing multiple route options with real-time departure boards.
Service hours: The MTR operates from approximately 6:00 in the morning until 1:00 at night daily. Exact first and last train times vary by line and station. The MTR Mobile app has a dedicated first/last train search feature. On Christmas Eve and New Year’s Eve, the MTR typically extends service hours, though this is announced annually.
Lost property: If you leave something on a train or in a station, contact the MTR Lost Property Office at 2861 0020 (daily, 8:00 to 20:00). The main office is at Admiralty Station. The MTR also offers an online lost property registration form and, since July 2025, a delivery service in partnership with SF Express so you can have recovered items sent to your address.
Customer service hotline: For general enquiries, call the MTR hotline at 2881 8888. Live agents are available Monday to Friday 8:30 to 18:00 and Saturday 8:30 to 13:00, with an automated system available around the clock.
Typhoon service adjustments: During typhoon signals T8 and above, the MTR reduces and eventually suspends above-ground services while keeping underground sections running as long as safely possible. The MTR Mobile app and the MTR website publish real-time service updates during severe weather.
Accessibility: The MTR is one of the more accessible metro systems in Asia. 90 of 93 stations provide lift or ramp access from street level to the concourse. Portable ramps are available at all stations to bridge the platform-train gap for wheelchair users. Tactile guide paths are installed throughout every station for visually impaired passengers.
Cross-border travel: The East Rail Line terminates at two Shenzhen border crossings: Lo Wu and Lok Ma Chau. If you are planning a day trip to Shenzhen, the MTR is the most common way to reach the border. Note that fares to these stations are higher than standard MTR fares, and you will need a valid travel document to cross.
