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 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 A/C（short form for air conditioner). 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. Service history The Class 82 used to operate in a fixed 3-car formation for its regular service. During the 1995–1999 period it used to operate at peak hours in a 3+3 car formation. But this configuration was soon discontinued. Briefly from 2010
