35–38 minutes TPE–Taipei Main if you stick to the Airport MRT Express
The Taoyuan Airport MRT Express (purple train, no. 1000-series services) runs about every 15 minutes from roughly 06:00 to 23:00 between T1/T2 and Taipei Main Station for about US$4–6, and it suits solo or light-luggage travellers who just want a predictable clock-to-clock ride into town.
From both T1 and T2, follow the Airport MRT signs down to the B2/B3 level; the Express and the all-stop commuter trains share the same physical platform, and real-world timing on r/taiwantravel threads puts the Express only 4–6 minutes faster than the commuter over the full airport–Taipei Main run.
Seats on the Express are 2+2 with luggage racks at the car ends, and Reddit users note that racks can fill up during morning and late-evening long-haul banks when multiple widebodies land within 30–45 minutes, so with a 25 kg checked bag you might end up keeping it by your seat.
Fares run around NT$150–NT$180 (about US$4–6) from TPE to Taipei Main, and you can tap in with an EasyCard or iPASS as well as buy a single-journey token from the machines next to the gates in both terminals.
Step-by-step: using the Taoyuan Airport MRT Express
- 1. Clear arrivals and find the MRT level. From customs in T1 or T2, follow purple “Airport MRT” signs down to the basement; expect a 5–10 minute walk with escalators and at least one elevator if you have wheels.
- 2. Buy or tap your fare. At the B2 concourse, use the ticket machines to buy a token to “A1 Taipei Main Station” or tap an EasyCard/iPASS at the gates; the screen will show the NT$ fare to A1 before you confirm.
- 3. Check the overhead board for train type. On the shared platform, look for “Express” vs “Commuter” in English on the LED boards and train fronts; locals advise just boarding whichever comes first unless a 5-minute difference matters to you.
- 4. Stow luggage and sit tight for 35–38 minutes. On the Express, use the dedicated racks and expect a non-stop-ish run with only a few skips; user-timed rides clock airport–Taipei Main at just over half an hour.
- 5. Transfer smartly at Taipei Main. At A1 Taipei Main, it can take 10–20 minutes to walk underground to the red or blue Taipei Metro lines, and Redditors sometimes bail earlier at New Taipei Industrial Park Station if their hotel sits on the Zhonghe–Xinlu Line.
What regulars do and watch-outs
Regulars on r/taiwan often ignore the Express branding and simply take the next purple-line train toward Taipei, pointing out that a missed Express plus 15 minutes of waiting wipes out its 4–6 minute timing edge over the commuter.
Several trip reports mention that late evenings the pattern shifts to more commuter runs and fewer Express departures, so if you land close to 23:00 you may see only all-stops trains listed and should grab the first one rather than hunting for an Express that is no longer running.
The Airport MRT offers in-town check-in for some airlines at Taipei Main’s A1 station, but r/taiwan users warn that desks for carriers like EVA and China Airlines can close several hours before the last train, so check your specific flight’s cut-off time and don’t assume you can tag bags at the last minute.
Signage for the Airport MRT inside Taipei Main Station itself draws consistent complaints, with some travellers reporting 15–20 minutes just to find the correct basement level, so on your return to the airport, pad an extra 20 minutes on top of the 35–38 minute train ride before your check-in deadline.
