Taiwan Railways is operated by Taiwan Railways Administration Organization and acts as an important role in Taiwan's transport system. TRA routes circulate the entire island forming a loop rail alignment with branch lines stopping at suburban country areas. TRA is not as fast as HSR but more affordable with many more stops at city central making transits more convenient.

Trains are divided into five classes from faster to slower services. The classes are Tzu-Chiang (most expansive), Chu-Kuang, Fu-hsing, EMU and Express. The first 3 classes offer assigned seating, standing tickets to be sold after seats are fully reserved. EMU and Express don't offer assigned seating.
Fares differ on the number of stops in between for all train classes. Make sure the train ticket you purchase stops at your desired departure station and destination station.

Taiwan Pass is available for travelers of all nationality and can be purchased at all major TRA stations. The Pass consists of 7 slots, effective any date starting from 60 days within the purchase and valid for 15 days from first date of use. Taiwan Pass for Adult is $1706 and Children $853, 15% discount on the $2006 fare of Tzu-Chiang Taiwan Pass.
Present your Pass at any station ticket office for designated seat arrangements. There are no limit boarding times or train classes but your travel route must follow your first travel direction (southbound or northbound) and going in loop. Your Pass is valid for 7 stops, you can chose your departure and arrival stations but routes cannot be repeated, if you chose other form of transportation in between your routes, the additional fare will not be compensated.
