 I choose Option 4 because it is faster and convenient. I arrived at Terminal 2. Follow the sign to Taoyuan Airport MRT. Buy the ticket at the vending machine. The machine does not accept the NT$ 1000 banknote. Fortunately, I had NT$100 banknote. Touch the screen where you would like to go to. I chose Taoyuan HSR Station (A18). There is only commuter train to this station. Free wifi is available on MRT.

Follow the sign to Zhongli.

 Arrived HSR Taoyuan Station. Buy the ticket and check timetable. You must see the platform number on the board. You can buy advance online ticket on Taiwan High Speed Rail website or from agent. I recommend to buy the ticket on Kkday (HSR Ticket) because no need to specify the travel time and also get the discount. 


Look at the car number on ticket and follow the sign to that number. The sign on the left shows the car number 1-6 and on the right shows car number 7-12. My ticket showed car number 4 so I went to left side and go to that platform number which already checked from the timetable . 

If you would like to go to TRA Taichung, follow TRA sign after get off HSR Taichung Station.


Here is TRA timetable from TRA Xinwuri Station to TRA Taichung Station (NT$ 15).
If you would like to get off at the front of TRA Taichung Station, please use exit no.2 or 3.
