At our stand, we presented modern devices for all kinds of railway vehicles – trains, metro vehicles, and trams – as well as electric buses and trolleybuses. Additionally, as many as four vehicles equipped with our power electronics were displayed on the fair’s exhibition tracks, including the Dragon 2 electric locomotive and the new hybrid Impuls 36WEh vehicle with a drive and power supply manufactured by Medcom. The remaining vehicles presented at Gdańsk’s exhibition tracks included two trams equipped with Medcom’s devices: the Moderus Gamma 2 low-floor tram for Poznań and the Twist for Gorzów Wielkopolski.
Medcom wins Grand prix for innovative and eco-friendly devices for public transport
The first day of the fair was concluded with the ceremonial TRAKO 2019 Gala, during which the winners in the competitions were handed their prizes. Our company received two first prizes and a distinction from the fair’s organisers and a special award from the Rzeczpospolita daily’s editorial team and the logistyka.rp.pl portal for its contribution to the development of eco-friendly, zero-emission public transport.
“As a company developing on the Polish railway market for more than 30 years, we have witnessed and participated in its dynamic growth. The position of our sector is also reflected in the growing recognition of the TRAKO trade fair. The Gdańsk fair is one of the most important events in the railway transport industry, which is why we are all the more happy about the fact that Medcom has had the chance to be the event’s strategic partner, basically from the very beginning,” says Joanna Nichthauser, Medcom.
Medcom’s awards at TRAKO 2019:
- Professor Jan Podolski Award in the railway stock parts, sub-assemblies, and equipment category for the PSM-145 SiC static converter for the metro in Turkey. The award is given to the best products and most innovative technological solutions for electric traction in public transport systems.
- Professor Czesław Jaworski Grand Prix of the Polish Association of Engineers and Technicians of Transportation (SITK RP) in the Vehicles category for the PSM-175 SiC static converter for Newag’s Dragon 2 locomotive. The prize is awarded for outstanding accomplishments in the application of modern technologies and devices in electric traction.
- Distinction in the Professor Józef Nowkuński Award competition for the drive and auxiliary power supply for EMUs powered by 25 kV traction for Tunisia.
- The award from the Rzeczpospolita daily’s editorial team and the logistyka.rp.pl portal for contributions to the development of eco-friendly, zero-emission public transport and for the ability to use new technologies and alternative energy sources in public transport.
Vehicle premieres at TRAKO – the hybrid Impuls with power electronics by Medcom
The TRAKO fair saw the official premiere of the Impuls 36WEh multiple unit, which was equipped with Medcom’s electric propulsion system, power supply system, and the train control and monitoring system (TCMS).
The state-of-the-art propulsion system is intended for the power supply and control of the operation of two asynchronous propulsion engines (400 kW each) powering the wheel axles and generating 3x400 V voltage for supplying low-voltage circuits in the hybrid Impuls. Medcom’s drive is composed of two traction inverter boxes and two static converters.
“We designed and manufactured a state-of-the-art asynchronous drive and power supply system, making it possible to obtain high performance and reliability parameters in the vehicle. It enables savings and recovery of the energy generated during braking by returning the energy back to the overhead contact line powering the vehicle. Additionally, we used a liquid cooling system in the traction converters. The entire solution, along with the vehicle control, contributes to lower energy consumption, and ultimately lowers vehicle operating costs,” says Wojciech Drag, Medcom.
The electric multiple unit was additionally fitted with a “power pack” unit powered by a diesel engine, which enables the train to drive on sections of the route where there is no overhead contact line. It is the only solution in Poland as part of an electric multiple unit operating in a passenger transport system.
