This causes additional resistance to the movement of the train and also causes significant damage to the railway infrastructure of Ukraine in the case of freight traffic. To eliminate the friction between the brake block and the wheel when the train moves in the traction mode and when using inertia, it is advisable to use a modernized device developed according to the UkrDAZT technology, which allows to reduce the running resistance of the train. This leads to a reduction in the consumption of fuel and electricity for the propulsion of trains and at the same time allows to reduce the operating costs of rail transport for energy consumption.skhttp://creativecommons.org/licenses/by/4.0/freight wagonbrake blockswear of blocksefficiency of operationArticlehttps://doi.org/10.26552/tech.C.2023.2.19
