The train services operating between Zhubei and Houlong include the Taiwan High Speed Rail (THSR) and the Taiwan Railways Administration (TRA) services. The THSR, which features the high-speed HSR-700T trains, can reach speeds of up to 300 km/h (186 mph) and usually covers the distance in approximately 50 minutes. However, the route does not run a direct high-speed service; travelers need to connect via Changhua station for the fastest options. The TRA services, primarily using the EMU and Puyuma trains, offer speeds around 130 km/h (81 mph) and take about 1 hour and 15 minutes for the journey with more frequent stops. While the THSR offers a fast travel solution, the TRA provides a well-connected network with the flexibility of multiple stops along the route for those interested in local attractions. Both services offer comfortable seating, but the THSR caters more towards speed, while the TRA has more stops for regional accessibility.
