Locomotive Class 478 (M47)
This locomotive is designed for routing passenger and freight trains. Its resource is a 12-cylinder MB 820 Bb type diesel engine having maximum revolutions of 1,480/min. The vehicle is driven by a reversing and a shift gear, built in with one hydrodynamic and two torque converting gears, supported by cardan axles and axle gears. The vehicle was provided with train heating equipment. The heating equipment in the passenger wagons are supplied with electricity by way of a three-phase simultaneous generator. The heating voltage of the locomotive is 1,500 V (alternating current).
With the amount of shunting work on the rise, and the need for higher performance and improved working order, the transformation of these vehicles became necessary. Accordingly the locomotives were equipped with CAT 3412 E DITA and MTU 12V2000 R80 type diesel engines compliant with EURO2 requirements, modern VOITH L3r4 gear, auxiliary generators and air conditioning. The compressor was replaced with a new one, of a rotational system. The electric heating was removed from the vehicle during its transformation. These vehicles were designed to perform shunting services at stations and freight train services.
The transformed locomotives are currently used for shunting at stations, and on lines with a lower axel load for routing and transferring freight trains.
