Analysis of the state and prospects of the development of the freight wagon fleet of the Republic of Uzbekistan

Abstract

In non-ferrous metallurgy — a large branch of the economy of Uzbekistan — the indicators of production efficiency depend, first of all, on the degree of introduction of innovations in the production cycle [1–3]. Equally important for increasing the efficiency of nonferrous metallurgy is the transport infrastructure, since ore extraction, processing for the production of non-ferrous metals, further delivery of non-ferrous metals for the production of semi-finished products or finished products are related to transportation. In this regard, the main tasks set for the railway transport of Uzbekistan require a significant improvement in the technical and economic indicators of the railway industry as a whole for the further socioeconomic development of the country [4]. The construction of new railways and the electrification of railway sections, in accordance with the decrees and decrees of the President of the Republic of Uzbekistan [5–7], led to an increase in the total length of the main railways and the volume of freight traffic, which required the corresponding development of the freight wagon fleet. However, due to unsatisfactory condition and shortage of rolling stock on the railways of Uzbekistan, the fleet of freight wagons is not in a position to fully provide for an increasing volume of freight traffic [8]. The main factor leading to the critical condition of the inventory fleet of freight wagons is the annual cancellation of wagons without replenishment in sufficient quantities by freight wagons of modern designs, with modernized and upgraded units.
