The Importance of Railroad Freight Transportation and Its Correlation to Economic Growth

In this study, the railroad freight transportation and economic growth relationship in Turkey was examined using the econometric analysis for the period of 1984-2017. As a result of the econometric analysis, it was found that there is no causal relationship between railroad freight transportation and economic growth in the long run, while there is a causality relationship from railroad freight transportation to economic growth in the short run. In addition to causality tests, an econometric model was created using stationary series, and the OLS method was applied for this model. According to this estimation result, an increase in railroad freight transportation increases economic growth. When this result obtained from the OLS estimation and the findings obtained from the Granger causality test are evaluated altogether, it can be stated that an increase in railroad freight transportation accelerates economic growth in the short run in Turkey.

American Railroad Freight Cars: 100 Years of Progress, 1920-2020

This paper was written to commemorate the 100th anniversary of the ASME Rail Transportation Division, which was founded in 1920 and held its first meeting in St. Louis. It attempts to paint a picture of the U. S. railroad freight car and the engineering processes involved in its design and construction in 1920 and compare this with today’s designs and practices. Progress in freight car design has been evolutionary rather than revolutionary. The steel freight car had largely replaced its wooden predecessor by 1920 and the basic design of many cars was already in place. Exceptions being the Spine Car and the Well Car, which were entirely unknown in 1920. The Box Car has diminished greatly in importance and more specialized cars are now common. One important difference is that welding is now used extensively in freight car construction whereas in 1920 riveting was almost universal. An important change is the availability of electronic instrumentation to measure, record and analyze the load environment of cars. This has allowed the development of performance-based specifications and these have largely replaced the prescriptive standards used in 1920. CAD and FE analysis have revolutionized the way in which cars are designed, allowing much more refined analysis which has led to far lighter car designs. In 1920 virtually all Engineers were white men — this too is changing.

Automatic Control of Rail Freight Transport

In this paper, we have analyzed the results of development and implementation of an automatic identification system for the railroad freight cars intended to run on the Russian Railways. This identifier complies with the requirements of ISO 10374 standard and has improved performance in comparison to its prototypes.

A Simulation Research for Railroad Freight Car-to-Car End Impact Based on Numerical Analysis

A method of establishing a kinematic model for simulated railroad freight car impact based on the Runge-Kutta method is introduced in this paper. The model is solved based on numerical analysis to obtain the relationship of variables, furthermore providing a basis for determining the loading support and loading securement method.
