The train service from Taichung to Taoyuan features the Taiwan Railways Administration (TRA) and the Taiwan High-Speed Rail (THSR). The TRA's Puyuma Express offers a comfortable ride with speeds reaching up to 130 km/h (81 mph), completing the journey in approximately 1 hour and 30 minutes. This service makes several inland stops, including at Changhua and Taoyuan, which can be beneficial for passengers traveling to these areas.
In contrast, the THSR provides a high-speed travel experience covering the route at speeds of up to 300 km/h (186 mph), reducing the travel time to just 45 minutes. The THSR operates more limited stops, focusing mainly on major stations such as Taichung and Taoyuan. This makes it the optimal choice for those prioritizing speed.
Both train services offer various seating options, with the THSR featuring Standard and Business class accommodations, while the Puyuma Express offers standard seating only. The THSR is recommended for swift connections between major urban areas, while the Puyuma Express serves passengers needing access to intermediate locations.
