The KDZ1A "Chuncheng" was an early attempt at building an electric multiple unit in China with the participation of Changchun Railway Vehicles, Zhuzhou Institute and Kunming railway bureau. Development was completed in 1999 in time for the Kunming World Horticultural Exposition. As its predecessor, the KDZ1 never operated commercially, the KDZ1A became the first Chinese EMU to be in revenue service, although it was in service for only 10 years before being withdrawn.
