The route from Zhubei to Tainan is serviced by Taiwan's High-Speed Rail (HSR) and the conventional Taiwan Railways Administration (TRA) services. The High-Speed Rail primarily operates along this corridor with the newest model, the THSR, which can reach speeds of up to 300 km/h (186 mph). This service connects both cities in approximately 1 hour and 30 minutes with minimal stops, making it a preferred choice for those prioritizing speed.
On the other hand, the TRA provides a more traditional rail experience, utilizing express trains for the journey. Although slower, taking around 2 hours and 30 minutes, these trains often stop at additional stations, allowing for more flexibility and connection to smaller towns along the way.
Both train services offer comfortable seating and amenities, but for travelers looking for the fastest route between Zhubei and Tainan, the THSR is the most efficient option, while the TRA may appeal to those seeking to explore the countryside.
