The Role of FDI and Rail Transport in the Economic Development of Central Asia. This paper examines the role of foreign direct investment (FDI) and rail transport in the economic development of Central Asia. The paper begins by providing an overview of the economic development of the region, with a focus on the role of FDI. The paper then discusses the role of rail transport in the region, and the implications of the growth in rail freight between China and Europe. The paper concludes by discussing the challenges and opportunities facing Central Asia in the coming years. Central Asia has attracted significant FDI in recent years, due to the region’s abundant natural resources, its strategic location, and its improving business environment. FDI has helped to improve the infrastructure in Central Asia, and has also created jobs and boosted economic growth. Rail transport is also a key driver of economic growth in Central Asia. The growth in rail freight between China and Europe is a positive development for Central Asia, as it provides an opportunity for the region to become a major transit hub. However, Central Asia still faces a number of challenges, such as political instability and economic volatility. If Central Asia can overcome these challenges, it has the potential to become a major economic player in the years to come.

“…Papers [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] dwell upon securing the cargo on a railway car. For instance, paper [1] investigates the issues of securing the retention bars with fasteners (nails) and notes that the acceptable load on a single 150...200 (mm) long nail is 5 .…”

“…Authors [15] do not even use the concept of cargo shift or displacement, although it is such shift during transport that causes nails of retention bars to be pulled out and the lashing wire to sag and/or break. Paper [16] presents research into securing complex-outline cargo on a railway car, where the retention bar is inclined.…”

This paper dwells upon securing solid cargo on a railcar. Transverse cargo shift and forces of elastic securing devices. The authors sought to calculate the shearing force acting on the elastic securing elements and retention bars; the retentive forces that prevent cargo from shifting across the car (the transverse shift); the transverse cargo shift; the force of elastic securing elements as exposed to transverse forces. This study relies on the second law as applicable to relative motion for a frictional constraint, as known in theoretical mechanics. The paper presents the calculated shearing and retentive forces. The authors calculated the equivalent stiffness of elastic securing elements. They thus computed the transverse shift (displacement) of cargo and the elongation of each elastic element that secures the cargo. They also found the forces of elastic securing elements as exposed to transverse forces. It was thus discovered that the forces of the second securing pair were more than double the acceptable limit, which would cause that pair to break during transport. To make the second elastic pair stronger, one might double the number of retention-bar fasteners so that the forces of the second fastening pair wouldn’t exceed the limits. An example of calculation is useful in developing a new methodology for calculating the elements of cargo securing on a car. The calculation results proved that to ensure guaranteed safety and reliability of the transportation process, it is necessary to either increase the number of securing elements of the retention bar, or increase the number of elastic securing elements with subsequent recalculation of forces in all elastic securing elements.

Cargo securing on a railway platform, elastic and retention fasteners, longitudinal transport force of inertia, forces in elastic fastenings. Purpose: The paper presents the calculation of the longitudinal transport force of inertia; determines the longitudinal force perceived by the elastic elements of the cargo securing; determines the reactions of retention bars depending on the number of bars and fasteners (nail); calculates the sum of all holding forces; calculates the forces in the elastic fasteners when exposed to longitudinal forces. Research methods: To determine the forces in the cargo securing devices, existing calculation methods are used. Moreover, the formulas of these techniques are presented in a form convenient for calculation. Main results: The paper proves that according to the existing method, the force in all elastic cargo fasteners under the influence of longitudinal forces has the same value, regardless of the different arrangement of the geometric parameters of the fasteners in space. The forces in them are more than 1.6 times higher than the permissible values. The calculations of forces in the elastic fasteners, which are performed by the specified method, are given. The results of the comparative analysis showed that the forces in all wire fasteners, in contrast to the existing calculation method, have different values. However, the strength of the second pair of wire fasteners of both one and the other direction is not ensured - the force in them more than two times exceeds the permissible value (61/24.8≈2.5), which will result in their destruction during the cargo transportation. Conclusions and their significance for the industry: Existing calculation methods do not provide guarantee strength of cargo fasteners. In the future, to calculate the fastening of cargo by shippers in the railway industry, a new calculation procedure should be applied for the allocation and fastening of cargo on the car.
