Determining the possibility of using removable equipment for transporting 20- and 40-feet-long containers on an universal platform wagon

An important role in the market of transport services belongs to container transportation. Railroads, especially under conditions increased competition from road transport, must respond quickly needs and growing demand for transportation, including interstate traffic. Demand transportation can vary significantly during year, which testifies expediency introducing removable equipment on universal railroad freight cars that are involved deliveries containers. This paper reports design a frame structure platform could carry two 20-ft or one 40-ft container. The proposed technical solution does not require changes car its model; with decrease it would allow this be used main purpose.
 According current methodology, efforts operate containers have been determined. strength was estimated by finite-element method. maximum stresses arising 164.4 MPa; they occur corners stops attached stand-up staples platform. resulting stress values do exceed allowable ones. results calculating indicate sufficient strength. Requirements placing cargo rolling stock assume mandatory check fit dimensions, confirmed hosted them. makes possible abandon disposable fastening parts, improve safety increase competitiveness market.
