The Mugunghwa ho (Korean: 무궁화호) is the lowest-priced passenger train in the national railway network of Korea. It is now widely operated on the main railway section of South Korea that has not yet been electrified and part of the feeder railway. The train began operation on the Gyeongbu Line and the Cheongju Line on April 15, 2008. It is now running on most routes in southern Korea. The operation of the infinite flower number began on January 1, 1984. Before the Korean high-speed rail was opened to traffic in 2004, the endless flower was the most common passenger car in the area. On the rural route such as the Kyungboku Line, the Infinity Flower is the only train used and will stop at each station.
Unlike the high-speed train and the new village, the infinite flower number can accommodate more passengers and more stations. There are light regulators, personal reading lights, automatic doors, and seats and toilets that can be adjusted and rotated. Each train has a coffee cabin with a canteen and text leisure facilities such as computers, game consoles, karaoke rooms and massage chairs. The infinite flower name is named after the national flower of Korea - the infinite flower (wood).
