The KTM class 83 3-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 Brecknell Willis pantograph for electric pick up. Narrow gangways integrate the 3-car sets. Each car features 3 double-leaf pneumatic sliding doors at either side, and these make the KTM class 83 have the highest density of doors per rail-car in Malaysia.
Over the years, the KTM class 83 has been overhauled a number of times and its interior refurbished. However, its interior layout, consisting of longitudinal seating, has remained the same throughout its service life. Four sets of the Class 83 have been refurbished for the KTM Skypark Link. The colour was also changed from blue and yellow, to orange and grey.
With the withdrawal of the Adtranz/Walkers EMU, which served the Ampang and Sri Petaling lines, the KTM Class 83 is now the second oldest still-functioning electric multiple unit in Malaysia after the KTM Class 81.
