The vast majority of passenger rail transport in Poland is carried out by vehicles powered by electric traction. In case when a train needs to pass through a non-electrified section of the line, it is necessary to use an electric traction-independent vehicle, which, translated into the current situation, means using a vehicle with an internal combustion engine. The authors propose using a dual-drive 111DE locomotive for passenger rail transport, which can move on electrified and non-electrified railway lines. The article also presents data on the railway infrastructure and statistics on passenger rail transport in Poland. Considerations and justification for the use of a dual-drive vehicle are presented.

Paper presents analysis of intermodal rail transport in selected loading units. The brief description of the loading units is presented. The volume of intermodal rail transport of load units in European countries in 2021 is shown, taking into account mass of transported goods, transport performance and average transport distance. Goods in the intermodal transport are carried out in container, swap bodies, semi-trailers and road sets. The most frequently used loading unit is the container. Semi-trailers is the most often used loading unit in road freight transport. However, semitrailers are rarely used in intermodal transport in most European countries. In the case of Poland, the share of intermodal transport of containers and swap bodies by rail constitutes a significant share in the European market, however, the transport of semi-trailers and road sets is still a ratherunpopular form of transport compared to other European countries.

The article presents an innovative solution of a two-unit rail vehicle system for passanger transport with a dual-drive, diesel engine and electric motor. The vehicle was designed as a combination of two units, one dedicated to each of the two drive systems, where one unit provides electric drive while the other a combustion engine. The selection of engine and drive components was presented along with the aftertreatment systems used in the design. The provided solution was created in response to the dynamic needs of rail vehicle operators in the European Union who aim to reduce exhaust emissions without compomising the reach of the existing rail networks.

Track works typically require the use of special-purpose rail machines, in which the main source of propulsion includes high-power compression ignition engines. Reliance on these types of engines, which are characterized by a significant degree of wear and tear, relates to relatively high specific fuel consumption and the exhaust emissions of toxic compounds. Using such rail machines to perform modernization and repair works has a negative impact on the natural environment. The article presents test results of toxic compounds exhaust emissions as measured from a special purpose rail machine. The tested vehicle was a machine designed for profiling the ballast cess labeled as PŁT-500. The machine was classified as NRMM (Non Road Mobile Machinery) as well as used for profiling and cleaning the cess. A PEMS (Portable Emissions Measurement System) type apparatus was used for the emissions measurement. This made it possible to measure the exhaust emissions as RDE (Real Driving Emissions) of toxic compounds from the machine under real operating conditions. The obtained test results include the measured exhaust emissions of gaseous compounds: CO, CO2, HC and NOx as well as the vehicle fuel consumption while performing its track works.

The paper presents the possibility of using a VCR engine as a driving unit of a generating set in rail vehicles. Thermodynamic analyzes of the engine were also performed. For the purposes of the research, the piston path was generated in the dynamic simulation in Solidworks to study the processes occurring during the combustion process. This path was used to simulate the AVL Fire program for the same initial conditions. Different variants of the engine cam control with the same compression ratio were compared. The article analyzed the moment and the period of time that the piston remains in the Upper Dead Center (TDC).
