RWS Market: Diesel shunting locomotives
Express Service is the Eastern European leader in offering new shunting locomotives. Bulgaria based company has developed several series of diesel and battery powered shunters that cover most industrial, in-yard or even light train service duties.
MDD 5 diesel shunting locomotive
The newest, largest and most powerful MDD5 shunting locomotive was developed, engineered and manufactured at the locomotive plant in Ruse. It is one of the largest and most technologically advanced machines ever produced in Bulgaria.
Specifications:
- Total power – 960kW
- Wheelset arrangement – B’- B’
- Pulling force at the start – 240kN
- Nominal weight – 72t
- Fuel consumption at idle speed – 2.6 l/h
- Engine Environmental Compliance – Stage V
- Remote control
MDD 4 diesel shunting locomotive
MDD 4 meets all medium shunting requirements. It is powered by a 400kW Tier 4F engine thus the loco is the most eco-friendly diesel shunter in Europe.
It is homologated in Switzerland, Italy and Bulgaria and could obtain permission in most EU administrations. Locomotive is extremely economic with idle fuel spending of just 2l/h. Its mass is 42 tons and is optionally radio remote controlled. Of course – it is the most affordable loco of its class amongst all European competitor models.

MDD 3 diesel shunting locomotive
MDD 3 diesel shunting locomotive is the smallest two-axle shunter. It is powered by two synchronized diesel engines that deliver 300kW of power. Due to a good choice of gearboxes, vehicle top speed could be adjusted between 15 and 60km/h thus customers select the optimal tractive effort.
These locos are quite flexible not only in terms of top speed – their mass is adjustable from just 20 tons for metro and urban rail projects to 36 tons for heavy industrial shunting works. Hauling capacity is up to 1600 tons. This model is homologated in Ukraine, Kosovo, Macedonia but it is generally intended to perform in-yards at industrial sites, ports, factories.
