“…In this regard, tram traffic is actively developing all over the world 1 – 3 . The analysis of scientific and technical information shows that various technical solutions and innovations in the field of railway transport are usually implemented first in urban rail vehicles and later in other types of rail vehicles 4 , 5 . This trend also applies to the current development direction of railway transport, such as the low floor concept, which significantly impacts the design of undercarriages, traction drive-trains, brake systems 6 , 7 , and other components of railway vehicles 8 , 9 .…”

Urban railway vehicles are important means of transport in towns and cities due to their high capacity, power source, and low running resistance, which make them efficient for operation. Although these properties are considered advantages, there is still room for improvement in their operational efficiency. The main objective of this article is to investigate the impact of railway wheel design on the level of kinematic running resistance, which is expressed as the amount of mechanical energy losses during the interaction of wheels with rails. This research focuses on simulation computations of two variants of wheel design schemes: the traditional design scheme (TKS) and a perspective design scheme (PKS) characterized by a rotating flange independently of the wheel tread surface. Two undercarriage multibody models have been created, one with TKS and one with PKS, and simulation computations have been performed for running speeds of 10 km/h, 20 km/h, 30 km/h, and 40 km/h on track models in curves with radii of 20, 50, 100, 150, 200, and 250 m. The evaluated indicators affecting the level of mechanical energy losses were creep forces, slip velocities, and average power. The most important findings of this study are that the PKS design scheme resulted in lower values of all assessed parameters.

The article researches the development state of transport and transport infrastructure in Ukraine over last years. The research findings specify the topicality of the issue solution concerning the enhancement of transport and transport infrastructure in the conditions of structural, energy and financial crises, as well as considering a destructive influence of COVID-19 pandemic, occupation of Crimea, an anti-terrorist operation in East of Ukraine and a full-scale intervention of the Russian Federation started on February 24, 2022. Such methods of improving transport and transport infrastructure development in Ukraine have been offered under the research findings: the increase of public administration level with regard to all aspects of transport infrastructure; the use of proactive management; activation of searches and implementation of investment projects; introduction of an institute of public- private partnership on transport; partial and temporary decrease of tax burden; the development of complex solutions for transport services consumers under the infrastructure areas; optimization of transport pricing, etc.
