Purpose. The work is aimed at determining the influence of lateral displacement a freight car bogie, taking into account value movement speed on its main dynamic indicators and interaction rolling stock track. Methodology. quantitative assessment was obtained by method mathematical computer modeling. design scheme takes peculiarities cars as part train: possibility all modes body vibration in s...

In paper has been carried out to develop a load-bearing floor increase the carrying capacity of solid-body rail freight car. An analysis structures made it possible formulate hypothesis that car should have different cross-sectional shape. As result, was proposed, making reduce consumption materials by 1 2%. The maximum equivalent stresses (according Mises) proposed in static are 210.7 MPa, whi...

In the movement of freight across the supply chain, terminals play an important role as points of transfer between different modes. The location of terminals is one of the most crucial success factors bearing directly and indirectly on the main stakeholders involved including policy makers, investors, terminal operators, freight operators, and the local community affected. There have been sever...

The paper presents a model for the collaboration among independent freight forwarding entities. In the modern highly competitive transportation branch freight forwarders reduce their fulfillment costs by exploiting different execution modes (self-fulfillment and subcontraction). For self-fulfillment they use their own vehicles to execute the requests and for subcontracting they forward the orde...

In modern transportation systems, the potential for further decreasing the costs of ful lling customer requests is severely limited while market competition is constantly reducing revenues. However, increased competitiveness through cost reductions can be achieved if freight carriers cooperate in order to balance their request portfolios. Participation in such coalitions can bene t the entire c...

Thanks to a direct operation on random variables and a suitable class of cumulative distribution functions, the network-wide computation of delay propagation in railway networks is enabled in short computation times. On this basis, new work procedures to evaluate timetable robustness during the annual capacity allocation phase, to assess the interactions between temporary speed restrictions and...
