KTM Komuter - Rolling Stock

Rolling Stock

The rolling stock consists of three versions of three-car EMUs added over the course of three years, beginning in 1994. The EMUs were the first in KTM's history. All Komuter EMUs operate in multiple-unit formation, running from overhead single-phase 25kV AC 50 Hz catenary supply, with two driving cars and 1 - 3 trailer cars in between. The EMUs were state-of-the-art, with remote-controlled pneumatic doors, Automatic Train Protection (ATP), train data recorder, wheel-slip control, GTO/IGBT traction electronics and regenerative braking. Up to the point of their introduction no other KTM motive power used these modern train control systems.

Designated by KTM as "Class 8x"s, the EMUs wear a yellow, blue and grey livery, a departure from the predominantly grey livery that KTM adopted on other locomotives and passenger coaches at the time. A handful of EMUs include full advertisements on the sides of their cars.

The original Komuter fleet consisted of the following models:

• 18 Class 81 EMUs (designations EMU 01 to EMU 18) manufactured by Jenbacher Transport in Austria-Hungary (1994/1995)
• 22 Class 83 EMUs (designations EMU 19 to EMU 40) manufactured by Hyundai (HPID) (1996/1997)
• 22 Class 82 EMUs (designations EMU 41 to EMU 62) manufactured by Union Carriage & Wagon in South Africa (1996/1997)

More rolling stock was ordered in 2010; 38 six-car EMUs were ordered from CSR Zhouzhou Electric Locomotive Co Ltd

Four of the EMUs have since been decommissioned following serious accidents that affected their structural integrity, while another five are not listed as serviceable. On paper, the number of serviceable units stands at 53 out of the original 62, although there are reports of far fewer trains. However, the actual number of trains is set to rise back to the original, as trains are being reconditioned.

Future Komuter fleet is expected to include:

• 38 Class 92 EMUs manufactured by China's Zhu Zhou Electric Locomotives Co Ltd
