Taiwan High Speed Rail Corp. (THSRC) announced Tuesday a new promotion offering deeper discounts to frequent travelers, but passengers purchasing the tickets will not be able to reserve their seats. The company said an existing promotion, offering passengers discounts of either 15 percent or 35 percent (usually for off-peak travel) on designated seats daily, will be replaced by the new program when it is launched on July 1. Under the new promotion, passengers can get a 15 percent discount on eight rides or a 52 percent discount for unlimited rides between two specific stations on the high-speed line, but all travel must be completed within 30 days. Passengers can buy the discounted tickets for 27 different sections along the 345-kilometer line, not including Taipei to Banciao. The bullet train now stops at eight stations -- Taipei, Banciao, Taoyuan, Hsinchu, Taichung, Chiayi, Tainan and Zuoying. Under the new 52 percent discount promotion, a 30-day unlimited pass for non- reserved travel between Taipei and Hsinchu will cost NT$8,230, nearly NT$3,000 less than the NT$11,100 currently charged based on the 35 percent discount. THSRC also said the new discounted tickets will be able to be used on national holidays and weekends, unlike discounted tickets under the current plan. Although the 52 percent discount targeting commuters appears attractive, THSRC recommended that only those who take the train daily should take advantage of the deal. Meanwhile, starting July 1, the company will also increase its scheduled trains 892 per week from the current 879, with the additional trains to be operated during peak hours.
