“…The paper also presents the calculations of energy demand and data on components for the discussed drive system ensuring that at least three heavy shunting tasks can be performed (Table 4). The weight of the entire new drive system was 9900 kg and its total volume was 16.5 dm 3 [15].…”

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.

“…In order to identify demands related to energy and power rating, driving profiles are derived and evaluated for each case, firstly a simulation-based and secondly a data-based analysis: 1) Qualitative operational data of shunting locomotive operators in Germany had been derived in a web-based survey. The answers were used to create driving profiles by combining generic shunting movements [3]. Afterwards, the created shunting scenario was simulated using a longitudinal dynamic simulation tool for trajectory calculation in order to obtain and evaluate speed and power trajectories [4].…”

Currently most shunting locomotives in Europe are equipped with diesel-powered internal combustion engines offering the advantage of being universally applicable and able to operate independently of overhead lines. Concerning international decarbonization goals, the hydrogen-based fuel cell hybrid powertrain can omit local CO2 emissions completely.For such novel technologies economic viability is a key factor to allow for rapid adoption by the market. At the moment, no standardized or unified energy and performance-related requirement profiles for shunting locomotives are available as a widely usable database in order to be used as simulative input for an in-depth performance demand analysis. Furthermore, shunting related specifications are more difficult to map than requirements for mainline rail services or other line haul services, since a wide range of operational demands have to be considered.

Traction power systems (TPSs) play a vital role in the operation of electrified railways. The transformation of conventional railway TPSs to novel structures is not only a trend to promote the development of electrified railways toward high-efficiency and resilience but also an inevitable requirement to achieve carbon neutrality target. On the basis of sorting out the power supply structures of conventional AC and DC modes, this paper first reviews the characteristics of the existing TPSs, such as weak power supply flexibility and low-energy efficiency. Furthermore, the power supply structures of various TPSs for future electrified railways are described in detail, which satisfy longer distance, low-carbon, high-efficiency, high-reliability and high-quality power supply requirements. Meanwhile, the application prospects of different traction modes are discussed from both technical and economic aspects. Eventually, this paper introduces the research progress of mixed-system electrified railways and traction power supply technologies without catenary system, speculates on the future development trends and challenges of TPSs and predicts that TPSs will be based on the continuous power supply mode, employing power electronic equipment and intelligent information technology to construct a railway comprehensive energy system with renewable energy.
