Abstract
The article notes that the main share of the costs for maintaining a fleet of freight cars falls on their current, depot and overhaul repairs. The cost of car repairing is significantly affected by the increase in prices for wheels, new and overhauled wheelsets. The paper explores ways to reduce these costs by increasing the life cycle of the wheelset and extending its service life. The proposals of a number of authors are analyzed to increase the hardness on the surface of the rolling wheel, to reduce the wear of the wheel crest, to make changes to the repair documentation, to introduce new IT services into the car repair production. Issues of the use of blockchain technology for management of the life cycle of wheelsets are considered. Proposals are given for participation of the university scientific community in solving the identified problematic issues.
