Purpose. The purpose of the work is to determine measures to improve logistics operations with the specialization of directions for cargo and passenger transportation by transferring part of the transit cargo flow to parallel routes. Solving the problem of choosing a rational distribution of freight and passenger transportation depending on the specialization of directions will allow to optimize the use of throughput and transportation capacity and investments in infrastructure development. Method. Optimization of the transport process during mixed transportation involves the possibility of separating cargo traffic from passenger traffic. The proposed method involves solving the problem of choosing a rational distribution of cargo and passenger transportation depending on the specialization of directions. The idea of such demarcation is based on the fact that on the railway network it is possible to distinguish stations between which there are several parallel train routes. The research was carried out on the railway network connecting Lviv and Kyiv. When solving the problem, various indicators were considered: the length of the route, the time of movement, the mechanical operation of the locomotive, the load on the track, and others. In addition, the boundary conditions were taken into account: the volume of passenger traffic, cargo traffic, the carrying capacity of sections and the permissible speed of train movement. Results. A mathematical model of the redistribution of train flows on the railway network has been developed, which ensures the rational operation of the railway track with minimal costs for the reconstruction of the railway. Scientific novelty. It has been established that in the case of traffic separation, the timing of repairs may be different due to lower traffic intensity, which allows you to focus on specific types of repair work, and not on all types of work at the same time. Although the general principles of the periodicity of repairs may remain the same in both cases, periodicity schemes may differ depending on many factors, in particular, the intensity of operation, the technical condition of the vehicle, the timing of repairs and the availability of specialized personnel. Practical significance. With the application of the new approaches proposed by the authors to solving the tasks, schemes for the rational distribution of cargo and passenger transportation at the closed landfills of the regional branches of the South-Western and Lviv Railways were established, which will allow determining measures to improve logistics operations and reduce operating costs for the transportation of cargo and passengers.

Today, green transport is a growing trend in terms of transport costs, CO2 emissions and satisfaction with logistics services. Green logistics is an environmentally friendly and sustainable logistics system that encompasses activities affecting logistics functions and processes, promoting the environment and the development of a circular economy. Rail transport is considered to be one of the least polluting modes of transport, but the fact that only electrified rail represents the concept of green logistics has been underemphasised, as the fleet consisting of diesel trains is a major challenge. This article aims to investigate the implementation of green logistics in railway transport in the case of Lithuania. The scientific literature, SWOT analysis, expert evaluation and parameter correlation methods were used to achieve this goal. An analysis of the internal and external factors of Lithuanian Railways in terms of green logistics has identified the main strengths of rail transport. These are environmental friendliness, electric trains reducing CO2 emissions, a strong focus on circular economy and others. The main weaknesses include the more extensive use of diesel trains, competition, etc. The external factors of the company show that the main opportunities are the reduction in net CO2 emissions to zero, the acquisition of more electric locomotives and others, while the main threats include an increase in energy costs or the complexity of implementing new technologies. An analysis of these factors has led to the construction of a SWOT matrix, which shows that the company’s strategy in the field of green logistics is quite strong, with more strengths than weaknesses. The results made it possible to identify the links between the individual implementation principles of green logistics in railway transport and provide strategic guidelines for the successful integration of green logistic principles into railway transport in Lithuania.

“…The main principle is to ensure the continuity and permanence of the protective, environmental, health and wellness, and aesthetic function of protective forest strips. This principle is ensured by the timely implementation of a set of organizational measures carried out by the relevant service of the railroad track (Baranovskyi et al, 2021;Chornopyska & Stasiuk, 2020;Kobylkin et al, 2020). Besides, possible dangerous environmental impact is monitored on the railway.…”

To reduce the harmful impact of railway transport on the environment and ensure environmental safety, railway enterprises develop and implement a wide range of environmentally effective measures annually. First, it concerns the protection of the territories adjacent to the railroad tracks from various types of pollution. These forest plantations are created for the protection of the railroad track from adverse climatic factors, as well as for the reduction of the railway's impact on the surrounding territories - to reduce the various types of pollution, and to protect from adverse aerodynamic effects. In order to investigate the protective properties of forest plantations, we presented their detailed characteristics on the section of the Lviv-Sambir railway line. This is the busiest railway line in terms of the number of trains, which connects the eastern industrial regions of Ukraine with the western part of the European Union. It transports the largest volumes of cargo, including hazardous ones. The effect of afforestation on reducing the heavy metals content in the soil of the impact area of the railway was determined experimentally. In all samples, the concentrations of heavy metals in the soil do not exceed the maximum permissible concentration standards: Cu-100, Zn-100, Pb-30, Cd-3.0 mg/kg3. However, there is a decrease in the heavy metals' content with the distance from the track. Differences in ingredient pollution depending on the placement of plantations were established. Thus, the concentration of heavy metals is higher on average from 2.6% to 29.9% in the areas on the windward side compared to the areas on the opposite leeward side. Therefore, forest vegetation intensively retains heavy metals and performs the function of a filter for the natural environment. Research has established a reduction in the parametric impact of railway transport. The level of protective plantings' effect on noise reduction along railway lines was determined. The highest noise levels of electric trains were determined at 95-94 dBA near the track, at a distance of 50-100 m the noise level remained high at 90-82 dBA, and at a distance of 150-200 m the noise ranged from 86 to 65 dBA; the highest noise levels of passenger trains were determined near the track of 92-91 dBA; freight trains ‒ near the track 93-92 dBA. The dependence of the noise level on the structure and condition of the plantations was determined. Thus, it can be stated that the existing forest plantations perform their phytomelioration functions and reduce the negative ingredient and parametric impact of railway transport. In order to protect the territories adjacent to the railway from pollution successfully, it is necessary to monitor transport sections constantly to ensure the sustainable development of the railway industry.
