designed by the Marubeni Corporation and jointly built by Hyundai Rotem of South Korea and Mitsubishi Electric of Japan. The maximum operational speed of the ETS fleet is 140 km/h but is designed to travel up to 160 km/h. The total length of each train set is 138 m and weighs 231.8 tons. Each carriage is 22.95 m long, 2.75 m wide and 4 m high. Each train set has a passenger seating capacity of 350 and includes on-board facilities including toilets, a buffet car, power sockets per two seats and two LED Televisions per car. Second Generation Nineteen sets of KTM Class 93 trains were ordered in two batches to expand the fleet as the electrified network expanded. All 19 trains are in service as of October 2019. The rolling stock was to have been put into operation for the launch of the ETS Express service between KL Sentral and Padang Besar, and the ETS Transit service between Ipoh and Padang Besar. However, reports of problems during the testing and commissioning of the train sets resulted in the then Malaysian land public transport authority, SPAD, not approving the trains for use in time for the launch of the two services on 10 July 2015 and 11 July 2015. As a result, two KTM Class 91 train sets were used for the time being, one for the ETS Express, and the other for the ETS Transit, allowing for just one trip in each direction for both services. The first four KTM Class 93 sets went into service on 10 October 2015. All sets from the first batch have entered service. The second batch differs slightly from the first, with a redesigned livery and a business class coach, a first for ETS services, and started operations with the launch of the new ETS Business Class in October 2019. These coaches were given the name Class 93/2. A third batch of 11 Class 93 is tendered in March 2022 in light with the completion of the Gemas-JB Sentral EDTP modification. Longest and fastest metre-gauge trains in the world The ETS trains currently travel up to 140 km/h on the electrified metre gauge rail line. Due to the gauge, the service can be considered a higher speed rail (HrSR) limited-express service. Similar services operate on 1,067mm (3 ft 6 in) narrow gauge railways in other parts of the world: the Kamome & Sonic
