The Class 91 is a type of electric multiple unit currently operating on Keretapi Tanah Melayu's Electric Train Service (ETS) since 2009. KTMB purchased a total of 5 sets worth RM 240 million from a joint venture between South Korea's Rotem Co. and Japan Mitsubishi Electric Corp in 2008. Each set has six coaches.[2]

All five train sets were designed by the Marubeni Corporation and were built by Hyundai Rotem of Korea and Mitsubishi Electric of Japan.[3] 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.[4]
