The train began operations in 2015 and transports tourists through Jeongseon County in central Gangwon-do.

[4][5] The "A" in the train's name comes from "Arirang" (a Korean folk song), and the words "amazement" and "adventure".

[6] The song is listed as an Intangible Cultural Heritage by UNESCO and sometimes regarded as an unofficial anthem of Korea.

[2] The train has four themed cars with large windows and glass walls; one is a sky room, one a tea room, and two of the cars are decorated in regional colors of red, yellow, blue and purple[7] representing Jeongseon's geographical features such as the Dong River and the mountain ridges.

[1] The train's exterior includes a purple color for the pulsatilla, Jeongseon's official flower,[5] and is decorated with curves that symbolize the Arirang melody.
