Taiwan has one of the most efficient, easy-to-use rail networks in Asia, split between a modern high-speed line down the flat, densely populated west coast and a slower, older conventional railway that circles the entire island, including the dramatically scenic — and much less developed — east coast. Between them, trains will get you almost anywhere in Taiwan that matters to a visitor.
Two separate systems: THSR and TRA
Taiwan's rail network is really two systems that visitors quickly learn to distinguish. The Taiwan High Speed Rail (THSR) is a single, purpose-built high-speed line running down the west coast from Taipei to Kaohsiung, calling at major cities including Taichung, Tainan and Hsinchu. The Taiwan Railways Administration (TRA) is the older, conventional network, which reaches far more stations — including central city stations the THSR bypasses — and is the only rail option for the east coast and many smaller towns.
The two systems use separate ticketing (though some THSR stations connect to a TRA station nearby) and are best thought of as complementary: THSR for fast west-coast city-to-city hops, TRA for everywhere else, including some of Taiwan's most scenic stretches of track.
The THSR: Taiwan's bullet train
The THSR runs the length of the western plain from Taipei to Kaohsiung in around 1 hour 40 minutes to 2 hours depending on how many stops a given service makes, reaching speeds of up to 300 km/h. Trains run extremely frequently — every 15 to 20 minutes for much of the day on core segments — making it one of the most convenient high-speed services anywhere for spontaneous travel.
Non-reserved cars are available on every train, and finding a seat is usually easy outside rush hour and major holidays; a reserved seat costs only a little more and guarantees a place. One quirk worth knowing: several THSR stations, including Taichung and Tainan, sit some distance outside the city centre they serve, requiring a short shuttle bus or connecting TRA train to reach downtown — factor this into journey planning. See our Taipei to Taichung route guide for a worked example.
The TRA: slower, cheaper, and everywhere
The TRA network reaches almost every town of any size on the island, including central-city stations the THSR skips, and is significantly cheaper. Trains range from fast Tze-Chiang limited-express services down to slow local trains stopping everywhere. For city-centre-to-city-centre travel on routes the THSR also covers, the TRA is often the more convenient choice despite the longer journey time, simply because it avoids the transfer to an outlying HSR station — see our Taipei to Kaohsiung guide for a worked comparison over a longer distance.
The TRA is also the only way to reach Taiwan's east coast by rail, since no high-speed line has been built there — a deliberate choice shaped by the island's mountainous geography, which makes the east far harder and more expensive to build through than the flat, urbanised west.
The scenic east coast
The TRA line down Taiwan's east coast, from Hualien through Taitung, is widely regarded as one of the most beautiful stretches of railway in Asia, running between the Central Mountain Range and the Pacific coastline with almost none of the west coast's urban sprawl. Hualien is the gateway to Taroko Gorge, one of Taiwan's most spectacular natural sights, and the east-coast line is the standard way visitors reach it from Taipei, typically in around 2 to 2.5 hours on a fast Tze-Chiang service.
Because the east coast has no high-speed line and a lower population than the west, trains here run less frequently and can sell out on weekends and holidays — booking ahead matters more here than almost anywhere else on the network.
The TRA loop: circling the whole island
The conventional network effectively forms a loop around the entire island, connecting the west-coast cities, the southern tip near Kaohsiung, and the east coast back up to Taipei. Few visitors ride the full loop in one go, but it is entirely possible to plan a circular itinerary — Taipei, down the west coast by THSR, across the south, and back up the dramatic east coast by TRA — that shows two very different sides of Taiwan on a single rail-based trip.
Tickets, passes and the EasyCard
THSR and TRA long-distance tickets are bought separately, either online (THSR has its own app and website; TRA tickets can be bought via its website or at stations) or at station counters and ticket machines. Both systems offer rail passes for visitors planning multiple journeys — a Taiwan High Speed Rail pass and various TRA passes exist for set numbers of days, worth comparing against point-to-point fares for your specific itinerary.
For short hops, local transport and even some TRA local trains, the EasyCard — Taiwan's contactless stored-value smart card, originally built for Taipei's MRT — is enormously useful. It works on buses, the Taipei and Kaohsiung metros, convenience-store purchases, and increasingly on TRA local and semi-express trains, letting you simply tap on and off without buying a separate paper ticket for short journeys. It is not valid for THSR or TRA long-distance express tickets, which still need to be booked separately.

Frequently asked questions
What is the difference between THSR and TRA?
THSR is Taiwan's dedicated high-speed line down the west coast between Taipei and Kaohsiung. TRA is the older, conventional network that reaches far more stations island-wide, including the entire east coast, which has no high-speed line.
Do I need to reserve a seat on Taiwan's trains?
On the THSR, non-reserved cars are available on every train, so a reservation is optional but recommended at busy times. On the TRA, faster express trains generally require a reserved seat, while some local trains are unreserved.
Can I use my EasyCard on the THSR?
No. The EasyCard covers local transport, city metros and increasingly some TRA local and semi-express services, but the THSR and TRA long-distance express trains require their own separate tickets.
Is the east coast train worth taking?
Yes — it is widely considered one of the most scenic rail journeys in Asia, running along the Pacific coast beneath the Central Mountain Range, and is the standard way to reach Hualien and Taroko Gorge from Taipei.
