The trains were imported to Taiwan in 2012; since 2013, they have been running between
Hualien and
Taipei, on the existing
narrow gauge tracks of the winding
Yilan line, where they reduced traveling time between the two cities from 3 hours down to about 2 hours. On 28 February 2013, the TRA announced that
Taitung would become a destination on the
Puyuma Express with official operations beginning 16 July 2014, in concord with the completion of electrification of the
Taitung Line. == Rolling stock ==
