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 (company)|Rotem]] Co. and Japan [[Mitsubishi Electric]] Corp in 2008. Each set has six coaches.<ref>{{cite news|last=Kong|first=Lester|title=Malaysia to get electric train sets by March|url=http://thestar.com.my/news/story.asp?file=/2010/1/22/nation/20100122110304&sec=nation|accessdate=29 September 2011|newspaper=TheStar|date=January 22, 2010}}</ref>

All five train sets were designed by the [[Marubeni|Marubeni Corporation]] and were built by [[Hyundai Rotem]] of Korea and [[Mitsubishi Electric]] of Japan.<ref name=bloom1>{{cite web|last=White|first=Stanley|title=Marubeni Gets $67 Million Malaysia Train-Car Order, Nikkei Says|url=https://www.bloomberg.com/apps/news?pid=newsarchive&sid=aGwXKvp1yE8o|work=Bloombery|publisher=BloomPUB|accessdate=19 July 2012}}</ref> 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 [[Irish gauge|broad gauge rail (1,600mm)]] while Malaysia has a metre gauge (1,000mm) system and are electrically powered.<ref name=maru1>{{cite web|last=Kamimura|first=Sanako|title=Order Received for a 30-Car Commuter Express Train in Malaysi|url=http://www.marubeni.com/dbps_data/_material_/maruco_en/data/magazines/pdf/2009/shosha_98.pdf|publisher=Marubeni|accessdate=19 July 2012|archive-date=4 March 2016|archive-url=https://web.archive.org/web/20160304141555/http://www.marubeni.com/dbps_data/_material_/maruco_en/data/magazines/pdf/2009/shosha_98.pdf|url-status=dead}}</ref>

==Operation== The class 91 operates in a fixed 6-cars configuration. Currently, class 91 sets are mainly used for long-distance intercity travel.<ref name=star2 /> In 2010–2012, 2 sets of KTM class 91 were being used for normal commuter use due to a shortage of trains. While in commuter use, long distance facilities such as toilets and cafes were closed and locked.

The Class 91 usually operates at its service maximum of {{Convert|140|km/h|4=|abbr=on}} and is known to sometimes speed at {{Convert|160|km/h|4=|abbr=on}} during regular service at certain stretches.<ref name=Star3>{{cite web|last=Leung|first=Fredie|title=Electric trains to reduce travel time|url=http://thestar.com.my/metro/story.asp?file=/2010/8/24/central/6862337&sec=central|work=TheStarOnline|publisher=Star|accessdate=19 July 2012}}</ref> Speed is limited partially by the use of narrow gauge.

Train schedule is categorically separated into a number of fixed classes with different ticketing structure afforded to travelling at particular times. i.e. travelling during peak would incur premium ticket cost whereas travel during off-peak mid day incur a discounted fare.<ref name=Star2>{{cite web|last=ROSHIDI ABU SAMAH|title=Ipoh-KL electric train fare RM30-35|url=http://thestar.com.my/news/story.asp?file=/2010/7/27/nation/20100727170250&sec=nation|work=TheStarOnline|publisher=Star|accessdate=19 July 2012}}</ref>

== On-board service == [[File:KTM ETS2.JPG|thumb|Interior of KTM Class 91|alt=|left]] All six cars have standard class only with reserved seats. The seats use red seat covers and arranged in a 2+2 fashion with a tray table and a power outlet facilities. The seats can be easily converted for wheelchair use should the need arise. There is an LCD TV in every coach for entertainment and wheelchair-accessible toilets are available in coach B and E. Bistro coach are available at coach C which sells drinks, light snacks and microwaved meals.

==Maintenance== The Class 91 is stabled and maintained at Batu Gajah Rail Depot in [[Perak]].

==Features== The Class 91 is one of the first trains in KTMs inventory to feature onboard displays displaying current speed. Train seating is optimised for long distance seating with minimal standing space. Fixed large seats are placed traverse throughout the coach. LCD Displays within coach show feature films, with sound muted but with subtitled English. During long-distance operations, as many as 7 attendants will attend the train set.

==Expansion== In the future, there are plans for an additional 20 sets.<ref name=star2>{{cite web|last=SHARIDAN M. ALI|title=KTMB plans to invest RM1bil in 20 more electric coaches|url=http://biz.thestar.com.my/news/story.asp?file=/2011/12/19/business/10120354&sec=business|work=TheStarOnline|publisher=TheStar|accessdate=19 July 2012}}</ref>

However, there are none currently being ordered. Recent orders suggest a different rail class to be introduced. The [[KTM Class 93|second generation ETS KTM class 93]] has been introduced to further expand the ETS fleet size.
