North American freight railroads are expected to experience increasing capacity constraints across their networks. To help plan for this increased traffic, railroads use simulation software to analyze the benefits of capacity expansion projects. Simultaneous operation of heterogeneous traffic further increases delay relative to additional homogenous traffic. Additional passenger trains can caus...

Determination of frictional condition the running surface and side top rail (lubrication) that ensures best interaction rolling stock wheels rail, reduces force action thus track stability reduced wear rails in curved tracks is relevant for all net.The objective research to determine influence surfaces on forces “wheel/rail” contact with various motion parameters (speed, radius).The theoretical...

Heavy haul freight railroads carrying bulk materials such as coal or iron ore are characterized by several unique challenges relating to investment in construction and maintenance as well as achievement of optimal operating efficiency. This paper examines heavy haul railroads around the world in a comparative context that highlights differences relative to operating parameters, degree of integr...

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...

Abstract The level of development railway transport is one the indicators economic state. If state regularly invests in large volumes infrastructure, it creates conditions for operation quality passenger and freight rail transport. Analytical comparison infrastructures key to understanding increasingly abysmal differences between infrastructure two countries. will be made mainly from Network St...
