The subject of the project is a locomotive platform with advanced multi-system propulsion systems in different combinations. The project assumes the construction of a modular locomotive platform allowing for any configuration of a selected version of the locomotive according to customer requirements. The locomotive platform will include the following configurations: diesel-electric (two-speed) Diesel approx. 1800 kW/2800 kW 3 kV DC for passenger or freight traffic, electric (multi-system) approx. 5600 kW – 15 kV/16.7 Hz + 25 kV/50 Hz + 3 kV DC for passenger or freight traffic, electric (multi-system) approx. 5600 kW – 15 kV/16.7 Hz + 25 kV/50 Hz for passenger or freight traffic, electric (multi-system) approx. 5600 kW – 15 kV/16.7 Hz + 3 kV DC for passenger or freight traffic, electric (multi-system) approx. 5600 kW – 25 kV/50 Hz + 3 kV DC for passenger or freight traffic The aim of the project is to develop design documentation for two selected types of locomotives and to build a demonstration of a representative type of locomotive. The demonstrator of the locomotive will be subjected to factory reception and tests under real conditions. The objective of the project will be achieved by using innovative methods of design and construction in a 3D environment that allows efficient layout of the equipment and optimisation of the locomotive mass. The final result of the project will be a demonstration of the locomotive in the form of a prototype built by PESA. The project’s results are to be transferred to the economy by developing a new product tested on a demonstration scale, making its commercialisation and starting serial production.
