You can check all available tickets using that "Inquire Available Tickets."
And I would keep checking as your departure data approaches. People cancel and the automatic cancel for online booked tickets that aren't bought occurs at midnight.
Yup. The only ones available as of now are the trains that take over three hours. Just a bit longer to drive to Hualien City. And the drive is dangerous and exhausting, with the chance of encountering construction on the mountain road being extremely high. It really is a shitty situation.
Yes the drive is dangerous as hell mostly due to the truck drivers and people overtaking at blind corners.
