TW Transit Radar brings Taiwan’s rail map, upcoming trains and journey planning together for everyday commutes and trips around Taiwan. FOUR INTERFACE LANGUAGES Choose English, Japanese, Korean or Traditional Chinese, or follow your device language. Foreign-language interfaces pair official English station names with Chinese for easy comparison with signs. Search by English or Chinese name, or station code. FIND YOUR NEXT TRAIN • Tap a station on the map to see departures. • Metro and light rail departures are grouped by direction, with express and commuter services identified. Show 2, 4, 6 or 8 trains per direction. • Check first and last train information for metro and light rail. • Taipei Metro Red Line uses official departure schedules, including Guangci/Fengtian Temple and short-turn trains. • For Taiwan Railways and THSR, choose a query time, filter by destination, and view stops and travel times. Taiwan Railways uses its official clockwise/counterclockwise directions; THSR uses southbound/northbound. • Pin a Taiwan Railways or THSR train and follow your journey above the map. Taiwan Railways delays and positions appear when available; THSR progress is estimated from its timetable. PLAN YOUR JOURNEY Plan across networks with estimated waiting and arrival times and clear walking-transfer information. Adult single-journey fare references are available for selected networks, together with travel times and connecting lines. Save favorite stations, return to recently viewed stations, or allow location access to find the nearest station. SUPPORTED NETWORKS Taipei Metro, Taoyuan Airport MRT, New Taipei Metro Circular and Sanying lines, Danhai LRT, Ankeng LRT, Taichung MRT, Kaohsiung Metro, Kaohsiung LRT, Taiwan Railways and Taiwan High Speed Rail.

Taiwan’s outline and office calendar are provided under the Open Government Data License. PRIVACY No account, ads or third-party analytics. With your permission, location is used only on your device to find nearby stations; your personal location is not uploaded. You can also decline location access and search manually.
