Artykuł omawia koncepcję obwodu głównego dla pojazdu szynowego zasilanego z trzech niezależnych źródeł energii – zespołu prądotwórczego, trakcji elektrycznej oraz bateryjnego zasobnika energii. Przedstawione zostały szczegółowo poszczególne tryby pracy pojazdu, z uwzględnieniem sposobu sterowania poszczególnymi komponentami obwodu w celu maksymalizacji możliwości odzysku i magazynowania energii w zasobniku bateryjnym.

In response to the market demand for modern special-purpose rail vehicles, an overview of the rolling stock available on the European and world markets was developed, along with an analysis of the scope of works they performed. The need for new alternative forms of propulsion in line with the development directions, taking into account EU and national environmental goals, was discussed. The paper presents a design of a proprietary modern special-purpose vehicle with an alternative drive. It discusses it compared to other special-purpose vehicles regarding their parameters and the viability of different drive systems, including hydrogen fuel cells.

Strict emission standards mean that the internal combustion engines used in means of transport must meet the standards for the emission of harmful compounds. For this reason, there is an increase in the use of alternative sources of propulsion, including rail transport. The article presents unconventional solutions of drive systems in rail vehicles using hybrid systems and fuel cells. The concept of the realizing project of a specialpurpose rail vehicle, which is to be able to be driven from three different sources, was presented. Considerations concerning the selection of the internal combustion propulsion system, which is to be used as an auxiliary in the vehicle, are described. The possibilities of installing the power unit on the vehicle were also presented.

W artykule przedstawiono badania dwukamerowego systemu wspomagania kierowcy podczas manewrów sprzęgania samochodu z naczepą typu gęsia szyja NGS-9,6 oraz podczas manewrów cofania całym zestawem. Dwukamerowy system wspomagania kierowcy SWK-2 wykorzystywany jest podczas sprzęgania zestawu pojazdów i pozwala na jednoosobowe wykonanie tego manewru przez kierowcę. Zamocowanie bezprzewodowej kamery pod rampą naczepy umożliwia kierowcy pełną kontrolę podczas cofania całym zestawem. Wpływa także na poprawę bezpieczeństwa pracy kierowcy oraz zwiększa bezpieczeństwo podczas wykonywania manewru cofania.

The paper presents the research of the two-cameras driver assistance system (SWK-2) during maneuvers of coupling the car with gooseneck type NGS-9.6 and during reversing maneuvers with the whole unit. The SWK-2 driver assistance system is used when coupling a set of vehicles and allows the driver to perform this as one-man operation. Fixing the wireless camera under the trailer's ramp allows the driver full control when reversing the whole unit. It also affects the improvement of the driver's safety and increases safety during the reversing maneuver.

The use of dual-drive rolling stock is a relatively new solution in the railway market. Vehicles with such type of powertrain are more versatile because it combines the advantages of using diesel vehicles and electric vehicles that consume energy from overhead electric traction. The concept of using such vehicles is highly innovative and has many advantages. However, the design and construction process is more complicated and requires more work than in the case of conventional systems. This article presents the methodology and process of selecting an engine-generator set for a dual-drive locomotive. Indicators and procedures crucial in the process of selecting a dual-drive system for a locomotive, were described and evaluated. All the above mentioned in the work were used during the real design process of a fully Polish locomotive with both diesel and electric drives. The locomotive in Diesel mode was to have an output power of circa 1560 kW for cargo transport. Calculations for the locomotive's power balance are included, showing power losses in the system and for locomotive's own needs. It has been shown that in cargo transport 77% of the maximum engine power is used as tractive power, and in passenger transport 58.6%.
