All five train sets were designed by the Marubeni Corporation and were built by Hyundai Rotem of Korea and Mitsubishi Electric of Japan. The design of the train sets follows very closely the IE 22000 Class of Ireland's InterCity trains. The major difference between the trainsets in Ireland and those used in Malaysia is that the Irish trainsets are diesel operated and use a broad gauge rail (1,600mm) while Malaysia has a metre gauge (1,000mm) system and are electrically powered.
