The train service connecting Huwei to Tainan predominantly utilizes the Taiwan High Speed Rail (THSR), specifically through the Tze-Chiang Express trains. These high-speed options can reach speeds of up to 300 km/h (186 mph), making the journey swift and efficient, typically taking around 1 hour and 30 minutes. On this route, the Tze-Chiang Express makes fewer stops, allowing passengers to enjoy a direct journey with minimal delays.
Alternatively, the local trains provide a slower travel option, with speeds ranging from 80 km/h to 120 km/h (50 mph to 75 mph). The local services take approximately 2 to 3 hours to complete the journey due to additional stops at smaller stations. While the THSR service is notable for its speed and comfort, the local trains cater to those who may need to reach specific intermediate destinations.
