6.2 ANALYSIS OF THE CAPACITY OF THE TASHGUZAR - BOYSUN - KUMKURGAN RAILWAY LINE FOR SWITCHING TRANSIT CARGO FLOWS BETWEEN CHINA, CENTRAL AND SOUTH ASIA

Abstract

The article deals with the construction of the Tashguzar - Baysun - Kumkurgan line, the reasons that contributed to the start of the construction of this line, the justification of technical solutions, the calculation of train running time, the throughput and carrying capacity of the section, the competitive ability with alternative transport in terms of international transportation.

Keywords: Tashguzar - Baysun - Kumkurgan line; capacity; carrying capacity

Until the nineties of the last century, railway communication in the northwestern and eastern outskirts of Uzbekistan was carried out through the territory of the Republics of Turkmenistan (Talimarjan - Boldir, Khojadavlet - Naymankul lines) and Tajikistan (Bekabad - Kokand lines). However, after the 1991 events, railways remained within each independent state, which inevitably affected the need for agreements between countries to carry out transportation. In this regard, the need arose to create a network of regional railway lines laid directly through the territory of the republic, connecting them with the center of the country, as well as to create a unified and independent railway transport system of the Republic of Uzbekistan.

The 223 km Tashguzar - Boysun - Kumkurgan railway line, built in 2003-2007, passes through Surkhandarya and Kashkadarya regions of the Republic. This railway line, in the context of current economic globalization, is of significant importance for the country's economic and industrial development, as well as for strengthening its foreign economic relations with neighboring countries, and for its future access through Afghanistan and Pakistan to the ports of the Persian Gulf [1,2].

The prospect of developing the existing Tashguzar - Boysun - Kumkurgan railway line as a link between China and South Asia may not provide large transit cargo flows between China and South Asia, as this Tashguzar - Boysun - Kumkurgan railway line has "narrow" areas that significantly reduce throughput and transport capacity, which must be subjected to increased line capacity when switching transit cargo flows between China and South Asia [3,4].
