Express Service manufactures battery-powered shunters since 2005. We meet the needs of most industrial shunting operations - low speed, safe, silent and emissions-free work environment.
Unlike diesel shunters, battery locomotives are slower and perform better only on level tracks due to the relatively small power. On the other hand – they have numerous advantages – lower price, lower running expense, practically no maintenance, silent operation with no emissions, and easier operation.
We build 3 types of battery-electric rail locomotives and one type road-rail vehicle.
Battery shunters are better solution for slower and repetitive tasks where there is a lot of idling time. Such are industrial applications of loading/discharging wagons, weight bridges, washing plants, UWL operations. Battery technology is a must for rail depots, wagons factories and for any indoor operation.
All our battery locomotives are driven by 2 or 3 synchronized AC motors and are powered by high capacity batteries. Our vehicles have built-in high-frequency chargers and are equipped with radio remote controls and comfortable cabins. ES and TSV battery shunters could be modified to 1520mm track gauge.
If your application requires greater power or higher speed, please consider our diesel shunting locomotives.
ES600 and ES1000 are our most widely used models. They have nominal shunting capacity of 600 and 1000 tons. However, on straight and level track ES1000 could move up to 2000 tons train. ES3000 is our newest development and is one of the most solid battery locomotives in the segment. It is a three-axle 47 tons vehicle with nominal shunting capacity of 3000 tons.
Battery shunters are driven by synchronized traction AC motors coupled to high-transmission ratio axle gearboxes. Thus, very high tractive effort is achieved given the low service speeds. ES vehicles top work speed is programmable and varies within 5-15km/h range. Locomotives’ own weight is up to 47 tons which ensures all-seasons duty and allows starting very heavy trainsets.
ES shunters stop coupled trains via regeneration (reverse motor current) and fill up batteries. This contributes to their excellent energy efficiency at duties requiring frequent start-stop operations or involving great idling time.
ES battery locomotives could have an optional pneumatic train braking system powered by screw compressor. Other possible options feature sanding installation, automatic coupler heads adjustable in height, standard UIC buffers.
Road and rail shunting locomotives have some advantages when operating in confined spaces. Two-way vehicles could de-rail and shift track if needed.
However, these vehicles lack the rigidity of real locomotives’ construction. Their design doesn’t feature real locomotive wheelsets (like in ES battery vehicles) thus reducing project life and increasing maintenance. Despite this we aim to integrate in TSV600 only qualitative components, reliable hydraulic system, and good electronics.
Nominal shunting capacity of TSV600 is 600 tons and the maximal one is 1000 tons. There is a comfortable driver’s cab, hydraulic and regenerative brake systems and many other features upon customer’s request.
