The K.R.T. Girls (Chinese: 高捷少女) are four anime-styled characters that serve as mascots for the Kaohsiung Mass Rapid Transit, a rapid transit system which covers metropolitan Kaohsiung, Taiwan. The girls consist of Siao Chung (小穹), who is depicted as a station worker at Yanchengpu Station; Amelia, a half-Taiwanese, half-German girl who works as a train driver; Chieh Er (婕兒), a train mechanic; and Nai Nai (耐耐), a Vocaloid-powered train announcer.[1]
