The route from Tainan to Zhubei is serviced by the Taiwan High-Speed Rail (THSR), specifically the THSR series, which is known for its rapid transit capabilities. The high-speed trains can reach speeds of up to 300 km/h (186 mph) and typically complete the journey in around 1 hour and 30 minutes, making it an efficient option for travelers. These trains are equipped with comfortable seating and provide onboard amenities such as Wi-Fi and refreshments. There are also options for both standard and first-class seating to cater to different preferences.
In addition to the THSR, traditional railway services operate along this route, taking longer with travel times averaging around 2 hours and 30 minutes, making several stops at local stations. While the THSR is prioritized for its speed and comfort, the regular services provide a chance to see more of the local scenery and environment. Overall, the THSR is best for those who prioritize speed, while the regular services may appeal to travelers interested in a more leisurely journey.
