“…In the market context, a certain barrier to the development of railways is the difficulty of new carriers entering the market -high cost, licenses, access rights to infrastructure, low level of rolling stock availability. Although the railway is characterised by high transport capacity, it is often treated mainly as a substitution branch for road transport (Abramov et al, 2022).…”

The aim of the study is to assess the scope of the impact of the COVID-19 epidemic on the rail transport market in Europe. To this end, both the passenger and freight transport market were analysed. The period under study covers the years 2019-2022. The COVID-19 epidemic has affected all European countries; and this extends to the demand and supply side of all modes of transport, including rail transport. Restrictions implemented in various areas of economic activity caused Railways to lose a significant part of their passengers. In 2020, the number of passenger-kilometres decreased by an average of 48% compared to 2019. Countries such as Ireland and the United Kingdom saw the biggest change (a decrease of 65%). With regard to the transport of cargo by rail, the scale of the restrictions was already significantly smaller. As a result, the volume of transport performance expressed in tonne-kilometres decreased in 2020 by 7% compared to 2019. The years 2021-2022 represent the end of the reconstruction of the railway market, where the number of passengers transported by rail and the rate of rail use increased significantly and widely. Countries such as Germany, Spain and France have taken initiatives to promote public transport, mainly railways. For the further development of rail transport, it is necessary to continuously improve the quality of services, reduce journey times, improve the accessibility of modern rolling stock and integrate rail with other regional, urban and suburban rail networks and other modes of transport.

“…Their experimental results showed that their proposed method was practical compared with existing empirical methods. Abramov et al [28] studied the practical impact of freight rates on traction fuel and energy expenditure and the optimization of freight train speed based on relevant constraints. Huang et al [29] proposed a two-stage entropy method based on the historical data of an index system to select railway express service stations.…”

In light of the improvements to the capacity and timeliness of heavy-haul railway transportation that can be organized through group trains originating at a technical station, we address a group train operation scheduling problem with freight demand importance via a newly proposed mixed integer programming model and a simulated annealing algorithm. The optimization objective of the mixed integer programming model is to minimize the weighted sum of the transportation cost and the total cargo travel time under the condition of matching freight supply and demand within the optimization period. The main constraints are extracted from the supply and demand relations, the cargo delivery time commitment, the maintenance time, and the number of locomotives. A simulated annealing algorithm was constructed to generate the grouping scheme, the stopping scheme and the running schedule of group trains. A numerical experiment based on a real heavy-haul railway configuration was employed to verify the efficacy of the proposed model and heuristics algorithm. The results show that the proposed methodology can achieve high-quality solutions. The case results reveal that the freight volume increased by 2.03%, the departure cost decreased by CNY 337,000, the transportation cost which results from the difference in the supply and demand matching increased by CNY 27,764, and the total cargo travel time decreased by 40.9%, indicating that group train operation can create benefits for both railway enterprises and customers.

“…For this reason, plans, considerations, simulations, optimizations [2,54], predictions and real solutions for the use of HSR (High Speed Railway) for high speed freight transport [20,35,51,52,60] have been developed. Including comparative analysis of the use of air transport and HSR [47,56], as well as the punctuality of express parcels transport by various means of transport [32] and the selection of optimal locations of consolidation centers to reduce GHG [9], mainly on China example.…”

The e-commerce market is gaining popularity globally every year. This market also entails the need to deliver the purchased goods at a time that is affordable for the user. One of the solutions is the use of High Speed Railway (HSR) for freight purposes, which is characterized by a relatively low rate of environmental nuisance. Based on the latest available market data and a literature review, an extensive review of the use of HSR, including for cargo transport, has been performed. The article presents an analysis of the demand for express freight transport. The potential and the demand for freight HSR have been demonstrated. The activities and analysis concerning the use of HSR for freight transport were described. Rail freight transport in Poland, Europe and China are characterized. Data on the use of the HSR infrastructure in the world are presented. HSR vehicles use for the transport of goods were presented. The potential and possibilities of using freight HSR in Europe were described. Based on the data, the use of this type of transport seems justified for LDHV shipments when the delivery time is crucial for the user and when the railway infrastructure and rolling stock are properly adapted.
