A useful metro makes a city easier to explore: you can work out the fare, find a route and reach the places on your itinerary. This is VoyajeBoard’s editorial selection of ten systems to compare, not a statistical league table or a guarantee that one network will suit every traveler.
How We Chose And Ranked
We considered five practical questions for visitors when making this editorial selection:
•
Reliability you can plan around. On-time performance and short, predictable waits, so a transfer does not become a gamble.
•
Ease for a first-timer. Clear English signage, station numbering, and tap-to-ride payment that works with a card or phone you already carry.
•
Reach that matches your trip. Coverage of the neighborhoods, sights, and airport you actually use, with frequent trains.
•
Cleanliness, comfort, and safety. Air conditioning, platform screen doors, and a calm ride at rush hour.
•
Hours that fit real travel. Late or all-night service for the nights you stay out.
The order reflects editorial judgment rather than published numerical scores or a common performance dataset. Use the trade-offs below to compare systems for your own route, access needs and travel times.
At A Glance
Getting Around
Tokyo: Plan Across Operators
Tokyo’s subway includes nine Tokyo Metro lines and four Toei lines. Tokyo Metro’s ticket guide distinguishes tickets for its own network from combined products. For ordinary pay-as-you-go journeys, PASMO and interoperable IC cards such as Suica are useful on participating networks, but do not cover every service or extra charge. Check the operator, route, exit, and ticket scope before traveling, especially when changing to JR or a private railway.
Best For: travelers willing to plan the operator and station exit as carefully as the line.
Hong Kong: Plan The Airport Connection
Hong Kong’s Airport Express links the airport with Hong Kong Station in as little as 24 minutes, according to MTR’s service information. Keep the onward journey in your plan: MTR lists shuttles operated by selected hotels, not a universal free transfer to every central hotel. Confirm eligibility, timetable and any charge with your hotel, and check the current Airport Express fare and last train before booking.
Best For: travelers who value precision and a fast, painless airport run.

Singapore: Contactless Payment And A Last-Train Check
Singapore offers convenient bank-card payment, but the card still needs to be supported. SimplyGo’s current FAQ includes foreign-issued American Express, Mastercard, and Visa contactless cards and explains the conditions and fees. Check those conditions for your card or device rather than assuming every wallet works. For an evening journey, use the station and direction you actually need: SBS Transit’s first/last-train tables show why one network-wide closing time is not enough.
Best For: visitors who want a supported bank-card option and are prepared to check their last connection.
Seoul: Plan The Interchange, Not Just The Line
Seoul’s connected rail services make the actual route more useful than a single line or station count. The city’s transport guide explains fares, prepaid transit cards such as Tmoney, and the need to tap correctly for integrated fares. Check the fare category and any distance charge for your journey rather than converting an old fare into a fixed USD promise. Leave time for interchanges, and keep route information available offline instead of assuming every tunnel or carriage will provide uninterrupted connectivity.
Best For: budget-minded travelers and anyone who likes to navigate by phone.
Taipei: Separate The City Metro From The Airport Train
Taipei Metro’s ticket guide explains single-journey and stored-value options, including EasyCard. Follow posted rules, including the no-food-or-drink areas, rather than treating quiet or cleanliness as a guarantee about every ride. The airport link is a separate service: Taoyuan’s official visitor information gives 35 minutes from Taipei Main to Terminal 1 and 39 minutes to Terminal 2 on the express train. The stopping service takes longer; check the train and terminal before boarding.
Best For: travelers who want clear ticket choices and will distinguish express airport service from a city-metro trip.

Copenhagen: Small, Driverless, And Open All Night
Copenhagen’s Metro runs around the clock, which can be useful for an early flight or a late return. Check the operator’s live service information for planned work and lift availability before relying on a journey. Do not extend that overnight claim to every rail network: in Chicago, 24-hour train service applies to the Red and Blue lines, not the entire system.
Best For: night owls and anyone who lands or leaves at an odd hour.
London: Use One Card Or Device Consistently
London’s useful feature for many visitors is pay-as-you-go payment with a supported contactless card or Oyster. TfL’s capping guide explains daily limits and a fixed Monday-Sunday weekly period. Use the same card or device consistently and touch in and out where required; a phone and its physical bank card are not interchangeable for that purpose. Check eligible journeys, zones, and foreign-card or device conditions. For late travel and step-free access, plan the particular service rather than assuming every line runs overnight or every station has a lift.
Best For: visitors who can use one supported payment method throughout their journeys and check the routes covered.
Paris: Check Tickets, Airport Fares And Access
Paris Metro, regional rail, and airport journeys do not all use the same fare product. For ordinary metro, train and RER trips, buy the appropriate ticket on a Navigo Easy pass or compatible smartphone. Bank-card payment has a limited rollout, not network-wide tap-to-ride: the operator’s rollout guide distinguishes bus and funicular use, the Orly exit-payment service and later rail deployment. Airport journeys require the appropriate airport ticket or another valid fare product. Check current ticket rules before traveling. The catch: older lines can be cramped, and many stations have stairs rather than elevators, so heavy luggage is a chore.
Best For: walkers and sightseers who want to hop on and off all day.

Madrid: Load The Right Ticket On The Right Card
Madrid’s Line 8 connects Nuevos Ministerios with the airport, as described in the official visitor guide. Check any current closures and the fare product for the journey. The regional transport authority describes Multi as a contactless card that holds tickets. That is not a blanket promise that any bank card can be tapped at a Metro gate. Load a valid product and check airport supplements or pass inclusions; the cost depends on the journey and ticket, not the system’s reputation for low fares.
Best For: travelers who want to compare a suitable ticket or pass for their route, including any airport connection.
Moscow: Station Architecture And Important Travel Limits
Station architecture is the reason Moscow appears in this editorial selection, not an invitation to ignore travel advice. Checked November 1, 2026: the UK FCDO advises against all travel to Russia. Consult your own government’s current advice before making any plan. Its money guidance states that Visa and Mastercard cards issued outside Russia do not work in Russian shops or ATMs. Consult the Metro’s current ticket information about Troika and top-up methods; do not read a transit card’s availability as a solution to wider payment, entry, or safety restrictions.
Best For: researching station design. Inclusion here is not a recommendation to travel against official advice.
Where The Famous Names Land
Leaving a network out is not a measured verdict on its quality. New York, Berlin, Barcelona, and Shanghai can each be the useful choice for a particular visit. Compare the actual destination, hours, changes, accessibility, and fare rather than treating this editorial order as an independently scored assessment of reliability or cleanliness.

How To Pay And Ride, Wherever You Land
Before traveling, check five things: the correct fare product, your payment method, the airport connection, the final train or interchange, and step-free access where needed. A transit pass is useful only if its covered routes and validity suit your trip. Compare it with ordinary fares instead of assuming advance purchase always saves money or avoids every queue.
If a relevant destination guide offers a partner ticket, compare the listed product with the operator’s current rules before reserving. Inventory and inclusions vary; an airport service mentioned in this article is not a promise that every guide has a matching bookable product.
