The recently-finished Taoyuan Airport MRT will begin commercial service on 2 March 2017, after construction first started in 2006 and was delayed multiple times. Trains run from both terminals of Taiwan Taoyuan International Airport (A12 & A13) eastbound through New Taipei and Taipei to Taipei Main Station (A1) and southbound through Taoyuan City.
Travel time for express trains (purple, stopping at A1, A3, A8, A12, and A13) between the airport and Taipei Main Station is 30-40 minutes and are expected to run 4-5 times every hour (6 am-11 pm). Travel time for commuter trains (blue, every stop) is about one hour and will run every 15 minutes. Tickets between the airport and Taipei Main cost NT$160/person. Fares to other stations start at NT$30. EasyCard, iPass, and HappyCash are accepted. Tickets are 50% off during the first month of operation (2 March-1 April).
Passengers can transfer to Taipei MRT in stations A1-A3, to high speed rail in stations A1 (HSR Taipei) and A18 (HSR Taoyuan), and to regular railway in stations A1 (Taipei Main) and A23 (TRA Zhongli, not yet open). Passengers flying China Airlines, EVA Airways, Mandarin Airlines, and UNI Airways can check in and drop their luggage at Taipei Main Station for flights departing after 9 am on the same day.
Taoyuan Airport MRT is the first line (Blue line) of Taoyuan Metro to open. Three more lines (Green, Orange, and Brown) are being planned and will connect stations A10, A11, A16, and A21 of the Airport MRT.
