Pressing questions on the further perfection of elements of designs of a used railway rolling stock are reflected. The complex of the offered technical decisions is based on spent in the Belarus state university of transport researches in the field of an estimation of durability of elements of designs of freight cars in view of features loading them transporting by liquid and loose cargoes. Novelty and utility of design development proves to be true patents of Belarus for useful models and their use at manufacturing new and modernizations of existing elements of designs of a cargo rolling stock.
