[2][3] Puyuma Express was commissioned by the Taiwan Railways Administration in order to upgrade the Taiwanese rail system.

[4] As the mountains of Taiwan are a barrier to coast-to-coast transportation, motor travel is prone to congestion.

[6] The maximum operational speed of Puyuma Express is 150 km/h (93 mph), making it the fastest service of TR.

[8] 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.

Puyuma Express services use TEMU2000 series tilting EMUs purpose-built by Nippon Sharyo.
