Taiwan High Speed Rail said it will add northbound reserved seats on select Taipei-bound departures Sunday and Monday after Mid-Autumn return traffic exhausted standard inventory on key morning trains from Zuoying and Taichung within eight minutes of release, according to a service bulletin posted Saturday night and reviewed by InfoHandle. The move converts a handful of business-class rows and previously held contractor blocks into standard-fare reservations sold through the usual app and station kiosks—not standing-room zones used during Lunar New Year peaks.
Where exactly, what changed
Extra capacity targets trains 123 through 132 on the Zuoying–Taipei corridor and trains 203 through 208 linking Taichung to Taipei between 9 a.m. and 2 p.m., when freeway Bureau data show south-north vehicle flows spike on National Freeway No. 1. THSR will not add standing tickets on these services; standing blocks remain limited to separately announced holiday trains if wind speeds along the Changhua viaduct stay below operational thresholds.
Taichung station managers were told to open auxiliary ticket windows for elderly passengers who failed online lotteries, a crowd that grew after homestay operators in Sun Moon Lake reported Sunday checkout surges.
How to get there now
Travelers without reservations should monitor the THSR app for last-minute releases when no-show rates climb above historical averages on post-holiday Sundays—typically 3 to 4 percent on business rows. Alternative routes include conventional rail northbound from Chiayi and shuttle buses from THSR Taichung to Taipei when HSR seats fail; total trip time rises about 70 minutes but avoids freeway stop-and-go near Hsinchu science-park exits.
Foreign visitors using passport pickup at stations must collect physical tickets before gates; mobile barcode-only entry still requires a locally issued payment card on some kiosks, a friction point tourism desks asked THSR to simplify after inbound Mid-Autumn travel rose this year.
Cost without a lecture
Standard northbound fares from Zuoying to Taipei remain NT$1,490 off-peak; added cars do not trigger surge pricing. Carbon-conscious travelers carpooling four occupants still beat HSR per-kilometer emissions on paper, but holiday fuel queues at freeway rest stops often erase time savings—why families with strollers pay the rail premium.
Who lives along the line
Commuters in Hsinchu and Taoyuan complained on social media that holiday trains skip some local stops when running express recovery schedules. THSR said those patterns revert to normal Monday night timetables unless Typhoon Krathon remnants bring another round of torrential rain in the south.
What would change the picture
A second wave of outbound tourism next weekend could force THSR to redeploy the same cars southbound; maintenance windows shortened to keep sets circulating. MOTC officials urged travelers to spread departures across midday slots rather than clustering at 10 a.m., when load factors on the newest releases already exceed 98 percent in internal dashboards.
For Antonio Rizzo’s readers, the practical takeaway is procedural: refresh the app after 8 p.m. Saturday releases, keep conventional rail as backup, and assume Sunday evening platforms at Taipei Main will be shoulder-to-shoulder even if you hold a reserved seat—because the holiday ends for everyone at once.
