I did a quick comparison of train timetables and it appears that both the HSR and regular train take almost the same duration, because the firsst HSR is around 6.30 am. In addition, if I take the HSR, I still have to change trains between taichung and xinwuri and ershui stating and the walking negates the time gained from using a HSR.
Is my understanding of the timetables correct? Does anyone know any better way?
So regardless of whether I take the HSR of TRA railway from Taipei, the earliest I can reach checheng station is at 10.10am?
