Ik heb bij mijn taiwanese vriend geinformeerd of het mogeljik is om het eiland rond te reizen per trein in 1 dag: hier zijn antwoord
I think of course he might be able to take the train around TW within one day,
but not for ‘'traveling’', because at least as far as I remember, we do not
have the kind of train ticket (one ticket) for people to travel around TW,
people do need the destination from one to the other (I mean, not Taipei-Taipei),
and also, he definitely not able to see TW within one day, especially there are several
sub lines besides the main train lines.
However, if he really want to try, I would suggest him to buy the ticket (the slowest
train, because in that way, he will have chance to stop in all the small and big
stations) from the very north station (like Kee-long) to the very south station (like
Pin-don) and from the very south to the ease side of TW (or any other directions he wants),
however, in that way, he definitely not able to finish the trip in one day.
