The Taoyuan to Houlong route is primarily served by Taiwan's TRA (Taiwan Railways Administration) services, which include the local train and express options. The fastest available service is the Tze-Chiang Limited Express, which can reach speeds of up to 130 km/h (81 mph) and covers the distance in approximately 1 hour and 30 minutes. This train offers comfortable seating and onboard amenities such as food and beverages.
In contrast, the local train service, while slower, provides a more frequent option for travelers and takes about 2 hours to complete the journey. It makes multiple stops, providing access to smaller towns along the route.
Travelers looking for a swift transit will prefer the Tze-Chiang Limited Express, while those wishing to explore more regional locales may opt for the local train service.
