The cars that are operated on the railways of Ukraine equipped with axle boxes cylindrical roller bearings. Many years operating experience has shown they have insufficient durability. One reasons is uneven distribution load between rollers in bearings, caused by design features wagon bogies. possible ways to equalize loads rolling elements can be creation a box housing variable stiffness. arti...

In this paper, a Q-Learning method for trasfer scheduling of freight cars in a train is proposed. In the proposed method, the number of freight-movements in order to line freights in the desired order is reflected by evaluation value for each pair of freight-layout and removal-destination at a freight yard. The best transfer scheduling can be derived by selecting the removal-action of freight t...

In highly competitive shipping market environment, container network operators-Freight forwarders, companies etc. are concerned about design, development and deployment of optimized allocation model to achieve cost savings through improved storage yard operations, crane productivity, outbound allocation/distribution seaport terminals hence reduction in ships’ waiting times. this paper, we devel...

The increased human mobility, combined with high use of private cars, increases the load on the environment and raises issues about the quality of life. The use of private cars lends to high levels of air pollution in cities, parking problems, noise pollution, congestion, and the resulting low transfer velocity (and, thus, inefficiency in the use of public resources). Public transportation serv...

We analyse maintenance cost data for Swedish railway infrastructure in relation to traffic volumes and network characteristics, and separate the cost impact from passenger and freight trains. Lines with mixed passenger and freight traffic, and dedicated freight lines are analysed separately using both log-linear and BoxCox regression models. We find that for mixed lines, the Box-Cox specificati...

Different optimal designs of bogie bolster for model 18-100 freight car are examined in the article. There is an analysis existing designs. Full-fledged fatigue tests by method specified GOST 32400-2013 carried out on stand designed dynamic strength tests. The values experimental studies were compared with calculated ones, maximum loads from 735 to 755 kN. best results observed at a load 745 kN...
