Taiwan High Speed Rail will add extra trains to its timetable to handle demand around Double Ten National Day, Radio Taiwan International reported.

The broadcaster's headline read: "Taiwan High Speed Rail to add more trains for Double Ten Day traffic." RTI did not specify the number of additional services, the dates on which they will run, or the timetable changes involved.

The Taiwan High Speed Rail Corporation operates the 350 km high-speed line connecting Taipei in the north to Kaohsiung in the south, with intermediate stops at Banqiao, Taoyuan, Hsinchu, Taichung, Chiayi and Tainan. The route covers the most densely populated corridor on the island, concentrating demand sharply on national holidays.

What is Double Ten Day?

Double Ten Day, observed annually on 10 October, marks the anniversary of the Wuchang Uprising of 1911 that led to the establishment of the Republic of China. The date is Taiwan's National Day. Public offices close for the holiday, and residents travel in large numbers between cities, both for ceremonial events in Taipei and for family visits elsewhere. The result is one of the year's largest sustained intercity travel peaks, with demand concentrated on the day before, the day of, and the day after 10 October.

How does THSR normally handle peak demand?

The operator's standard weekday pattern runs services at roughly fifteen-minute intervals during peak periods across the eight stations from Nangang to Zuoying. At national holidays, the operator has typically supplemented the base timetable with additional early-morning and late-evening services, reinforcing the most heavily loaded departures in each direction. Reservations on the busiest trains usually sell out within days of the booking window opening.

Standing-room tickets have been offered on the most heavily loaded holiday services in past years, expanding capacity on individual trains without adding new departures.

What does the announcement leave unspecified?

RTI's report contained no direct quotation from THSR management. It did not state the number of additional trains being deployed, the operating dates of the supplementary timetable, or the eligibility terms for standing-room accommodation. The Ministry of Transportation and Communications, which oversees THSR's franchise, did not feature in the RTI report.

In past years, THSR has published holiday timetable supplements between four and six weeks ahead of the relevant travel date. On that pattern, the Double Ten supplement should appear in the coming weeks, with reservations opening shortly afterwards.

What is the context of demand?

Holiday peaks around 10 October have, in some years, overlapped with the Mid-Autumn Festival, producing a combined travel surge. THSR has previously responded to such overlaps with multi-day timetable supplements rather than a single-day addition. Whether this year's calendar produces a similar overlap will shape the scale of the supplement once the operator publishes full details.

THSR began commercial operations in January 2007 under a build-operate-transfer arrangement. The current operator, the Taiwan High Speed Rail Corporation, took over the franchise following a 2015 restructuring.

What happens next?

The operator is expected to publish its Double Ten supplementary timetable and open reservations ahead of the 10 October travel date. Specific details on additional capacity, affected departures and standing-room availability should emerge when that document is issued.
