You should be talking about high-speed rail rather than MRT.
1. MRT among Taiwanese people refers to urban rail transit, which is also commonly known as subway in mainland China.
2. Currently, there is no rail transit passing by Taoyuan Airport (please see point 3). To go to Hsinchu, you must first take the high-speed rail to Ubus (full ticket NT$30), first go to the high-speed rail Taoyuan Station, and then enter Buy a ticket at the station and take the high-speed rail to Hsinchu Station (standard carriage NT$130, journey time about 10 minutes).
It is not recommended that you buy tickets in advance, because you cannot estimate the time when Ubus will arrive at the High Speed ??Rail Taoyuan Station, and Taiwan High Speed ??Rail has a train frequency of approximately every 36 minutes, so there is no need to buy tickets in advance.
3. The Taoyuan Airport MRT Line is still under "construction". The route is divided into two sections: to Taipei Station (Taipei Section) in the north, and to Taoyuan County Taiwan Railway Zhongli Station (Taoyuan MRT Blue) in the south. Line), taking the three terminals of Taoyuan Airport as the watershed. If the construction period is not delayed and the survey and testing are successfully passed, it will not be open to traffic until 2014 at the earliest.
4. Taoyuan Airport is in Taoyuan County, Hsinchu Station is in Hsinchu County, and Hsinchu County is in the south of Taoyuan County. And when you talk about Hsinchu Station, do you mean Taiwan Railway Hsinchu Station (train) or High Speed ??Rail Hsinchu Station (high-speed rail)? The two stations are quite far apart. One is in the city center (Taiwan Railway), and the other is in the suburbs of Zhubei (High-speed Railway), which is still in a remote stage of development. The two stations are connected by the Neiwan branch line of Taiwan Railway which was just completed last year.
