The Class 82 was a type of sub-urban rail electric multiple unit that once operated by Keretapi Tanah Melayu on its KTM Komuter services. Each unit consists of two driving motor cars and a trailer cars. All were retired by 2012 after being replaced by the Class 92. Design The Class 82 was designed with a streamlined sloped head with two high beam lamps concentrated at the center top with two standard headlights at either sides. Route direction is indicated on the front of the train within a confined fluorescent lighted box using a lightly transparent plastic. The Class 82 have two double-leaf pressure plug doors per side each coach. The cab head is designed to be bottom heavy with the bulk of the power transformers and motors located beneath the coach, allowing saloon space to be maximised. The front outer frame is made of heavy carbonized steel which is capable of sustaining high impact. An ARR coupling system is used, which is compatible with all of KTMB's modern rolling stock. Unlike the latter Class 92, the Class 82 like its sister classes are endowed with multi-layered tempered glass that is of a higher degree of impact resistance. Description 22 three car sets were built and delivered by Union Carriage & Wagon of South Africa from 1996 to 1997. The Class 82 sets were deployed in stages, with the final set coming into service in December 1998. The KTM Class 82 three-car formation consists of two motor cabs at either end of the set and a single trailer car in between, the trailer car in between is equipped with a double-arm Z shaped pantograph for electric pick up. Narrow gangways integrate the three-car sets, allowing full walking from cab to cab. Each car features two double-leaf electric plug doors at either side. Printed route maps are displayed each doors, along with emergency stop levers. The Class 82 has a top speed of , which was similar to the top speed of the other EMU classes but significantly faster than the railbuses that were in use at the time. During normal operation, was the typical top speed with the average speed being around . The Class 82 was said to have better energy efficiency when compared to the Class 81. This was due to the GEC Alsthom regenerative braking system being used which gave better acceleration during runs. Overhauls & Refurbishment
