The Taiwan Railway e-booking app is the official mobile application released by Taiwan Railway Corporation, Ltd..
It provides you with the convenience of accessing online train ticket reservations, membership features, and various services offered by Taiwan Railway anytime, anywhere.
Features:
1. 24 hours fully integrated ticketing service online.
2. Seat reservation, online payment, order modification, and cancellation.
3. Easy access to live train info and timetables.
It might be useful. There is an English version. Though the interface is not very user friendly and error messages are still appearing only in Chinese. But the biggest problem is that it doesn't connect to any server on the TRA side so it's a completely dead app. Can't check schedules. Can't book tickets.
Then again the TRA website itself has also been down for four days now so I'm starting to wonder if their development and communication team is just a broom with a couple of googly eyes stuck on.
