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.

Company has 150 years of history and experience in locomotive technology. Express Service originated as a repairs and service company for locomotives but since 2002 series of new shunters emerged. Nowadays Express Service offers 3 series of diesel shunting locos and 4 types of battery-electric vehicles. All vehicles could be built within gauges between 1000 and 1600mm.

MDD 3 diesel shunting locomotives

MDD 3 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.

MDD 4 diesel shunter

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 5 series

This is Express Service latest development. It is a twin-engine diesel shunter that is intended to replace the aggressively ageing East-Europe shunters. It is Express Service first BoBo locomotive and is a great continuation to MDD 3 series.

ES battery-electric shunters

Battery traction offers very economic, clean and safe shunting. That’s why Express Service developed several series of battery-powered vehicles – both rail and rail/road ones. Battery locos have extremely low operation costs and are virtually maintenance free. They have numerous advantages over the diesel shunters and one major drawback – design speed.

Battery shunting locomotives are the best-selling products of Express Service. Through cooperation with its main customer – Hegenscheidt MFD from Germany – Bulgarian shunters are exported to many different locations in the whole world. Of course, all shunters are safety integrated with UWL machines of Hegenscheidt.

Apart from wheel lathes applications these shunters are mainly used in locomotive and wagon repair depots and workshops, rolling stock factories, industrial plants, ports, logistic terminals. Due to the relatively low design speed, ES vehicles offer great starting tractive effort. Thus, it is not surprise that shunting capacity of the different models is up to 4000 tons.

ES600 and ES1000 battery shunters

These two series are the most popular models. Their full-load shunting speed is up to 10km/h – their advantage is at slow, repetitive operations with a lot of idling time. Real life case studies account for less than €10,00 of energy costs per work shift!

These vehicles are built out of high quality components from world leading suppliers. All models could be fit with radio remote control systems and train pneumatic brake system is an option. AC motor controllers are liquid cooled and perform at their best for longer time compared to similar competitor vehicles. As a customer-oriented company Express Service offers to its partners the good chance to program the AC system as per their needs thus making ES the most open-sourced and customer friendly locos on the market.

ES two-axle battery locos own mass vary from 9 to 36 tons and power range is from just 12 to 130kW. Best price on the market is a well-known fact and leading quality is guaranteed through the many satisfied customers from the most demanding Western European markets.

Unlike most competitors Express Service does not offer rubber traction wheels. ES shunters technology sticks to the two-centuries proven wheelset principle. In fact, ES battery locos are smaller scale electric main-liners. True locomotive technology leads to better durability, longer design life and less wear and maintenance. Unlike other companies in the sector Express Service doesn’t employ off-road automobile components.

ES8000 and road/rail shunters

Based on the success of ES200, 400, 600, and 1000 series, Express Service has designed several types of special battery vehicles. A three-axle light shunter, extra heavy battery shunter, work vehicle with crane and platform – all these are based on the proven design of ES shunters.

To be in line with competitors offering Express Service has a series of road/rail shunters. Not so durable and needing more maintenance – such vehicles are still preferred by some customers. Traction capacity of two-way TSV series is up to 2000 tons.
