KTM Class 82

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. In 1996-1997, 22 sets, for a total of 66 cars were built and delivered by Union Carriage & Wagon of South Africa. The class 82 sets were deployed in stages, with the final batch, being operational as late as December 1998. The class 82 similar to its sister classes, operated in three-car formations. It was only during the height of KTM Kommuter 1999-2001 that, the KTM class 8x family saw three-plus-three formations.

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 25KV AC 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.
== Overhauls & Refurbishment ==
Over its operational life, the KTM class 82 has seen its life extended through, numerous schemes of overhauling and refurbishment. However, due to closure of Union carriage & Wagons’s international rail business saw an end to any future replacement parts for the class 82. Tropical weather which the class 82 proved more that than taxing for the class 82 with the premature failure of many irreplaceable parts. Although, there has been attempts to substitute parts with those of a different make, the economics and technological expertise were not on the side of the class 82, and the class 82 soon found itself in the precarious state of having to resort to cannibalize the parts of older sets in order to keep the remaining fleet in operation.
In 2012, an attempt of fresh refurbishments has seen a mixture of traverse and longitudinal seating being introduced with a heavy emphasis on longitudinal seating, in acknowledgement of the classes' main role being in an intra-city commuter. Although, this was a good attempt at making increasing the overall capacity, it failed to addressed a key fundamental problem, the sets were running without replacement parts and off the shelf replacement parts from other makes are incompatible with this class.
2012 also saw the introduction of the special hybrid train service, where diesel locomotives were made to pull these decrepit class 82 bodies with functional doors, lighting and AC. Since the power transformers and power pick up systems could not be replaced, the company elected the use of additional diesel generators affixed on hopper wagons to power up the EMU. In effect, it reduced the role of these sets to nothing more than unpowered passenger coaches, but its use still had better convenience than compared to KTMB’s traditional unpowered coaches, which typically tend to be those specifically designed for long-distance intercity use, i.e. the doors were narrow and few, with limited standing space while having an open emphasis on comfortable seating. As mentioned the class 82 is not like that, and was design specifically to meet its role as a sub-urban commuter and gracefully step up to its role as a commuter rail wagon.
