Commissioning of the freight wagons with increased axle loads is a guarantee of the further development of railways of the Republic of Uzbekistan

The aim of the study is to select rational axle loads rolling stock and establish conditions for their circulation on railways Republic Uzbekistan. In this work, research has been carried out assess indicators stress-strain state rail track elements from action with various axial loads. dynamic wheel rail, tensile stresses at edges foot, in wooden sleepers (rubber under-rail pads reinforced concrete) under linings, ballast sleeper, as well main area roadbed, were determined. obtained results studies determination assessment loading permanent way sub-grade bed condition not exceeding standard values made it possible permissible speeds movement freight wagons increased 25 27 tf Uzbekistan, depending design thickness layer, which will increase running carrying capacity most loaded sections railway network, reduce operating costs, volume traffic by create further development national transport implementation export transit potential.
