“…It is an environmentally friendly solution due to its usage having close to zero emissivity. Contrary to the combustion of hydrocarbon fuels, where the combustion products, in addition to steam and heat of combustion, include such harmful compounds as: CO 2 , CO, HC, NO x as well as particulate matter (PM) [4,17], the combustion of hydrogen result in the production of water vapor [26,27] and when the temperature is high enough also the formation of NO x compounds. Hydrogen can also be used in fuel cells, the so-called Fuel Cell Hydrogen (FCH) [5,24].…”

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 special-purpose 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.

“…The third way is to define emission factors based on CO 2 emissions or fuel consumption. The assessment of the toxicity indicators, which refer individual compounds to CO 2 emissions, is presented in [17]. This approach seems to be the most developmental at present.…”

The exhaust emission standards in force in various parts of the world for off-road vehicles are becoming more and more stringent. Therefore, research on the compounds of harmful exhaust fumes emitted by vehicles of this category is constantly being researched and activities aimed at limiting them are constantly being carried out. The basic problem in terms of measuring exhaust emissions is the approval tests of traction vehicles, which are carried out on engine dynamome-ters. Therefore, it is impossible to obtain reliable results concerning their actual impact on the natural environment. It is therefore advisable to carry out the tests in real operation conditions, as is the case for road vehicles for which RDE (Real Driving Emissions) tests are carried out. The latest Stage V emission standards push for the introduction of this type of test, but no limit values for toxic exhaust gases have been established and no test guidelines have been defined for as-sessing actual emissions. This article describes the issues related to the legislative guidelines for non-road vehicles in force in Europe, as well as the measurement tools used, such as mobile equipment for measuring emissions of PEMS (Portable Emissions Measurement Systems) and newly developed emission gates.

“…Vehicles of this type are not yet so popular a solution on the railway market. However, this solution can be used in any type of railway vehicles, including rail-road vehicles [20,21,34], locomotives [22], Multiple Unit (MU) [10], and auxiliary rail vehicles.…”

The use of dual-drive rolling stock is a relatively new solution on the railway market. Vehicle with such type of powertrain is 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 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 1,560 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%.
