John P. Parker played a prominent role in the Underground Railroad network that operated in southwest Ohio. Additionally, Parker held three known patents and displayed his products at regional/national industrial expositions. Parker’s engineering skills and business acumen, however, have largely been overlooked. A coalition comprised of faculty and students from the University of Cincinnati, members of the John P. Parker Historical Society, and corporate donors formed in 2006 to preserve the industrial legacy of this African American entrepreneur. This project demonstrates some of the benefits and pitfalls of such complicated undertakings.

AbstractThis study explores the relationship between railroad integration and regional development on the European periphery between 1870 and 1910, based on a regional data set including 291 spatial units. Railroad integration is proxied by railroad density, while per capita GDP is used as an indicator of economic development. The period under study is of particular relevance as it has been associated with the second wave of railroad construction in Europe and also coincides with the industrialization of most of the continent. Overall, we found that railroads had a significant and positive impact on the growth of per capita GDP across Europe. The magnitude of this relationship appears to be relatively modest, but the results obtained are robust with respect to a number of different specifications. From a geographical perspective, we found that railroads had a significantly greater influence on regions located in countries on the northern periphery of Europe than in other outlying areas. They also helped the economies of these areas to begin the process of catching up with the continent’s industrialized core. In contrast, the regions on the southern periphery showed lower levels of economic growth, with this exacerbating the preexisting divergence in economic development. The expansion of the railroad network in them was unable to homogenize the diffusion of economic development and tended to further benefit the regions that were already industrialized. In most of the cases, the capital effect was magnified, and this contributed to the consolidation of newly created nation-states.

Many cultural anthropologists have studied networks and how people reinterpret and attach symbols to these networks, pulling symbols from a grab-bag of collectively significant events and personages. As an ethnographer working for a new National Park Service program, I find myself involved in creating "networks" and affecting construction of "meanings," rather than studying the process as an outside observer. In the National Underground Railroad Network to Freedom, created by Congress, my colleagues and I affect and effect relationships between groups previously unfamiliar with one another or previously not considered to fit under one umbrella. It would it be putting on blinders to analyze "transformations of popular concepts of the Underground Railroad" without considering the National Park Service and other cultural resource managers' role in public education, historic preservation, and use of memory in exhibits and publications.

Chapter 2 scrutinizes Tlatelolco, site of the October 2 massacre. Its literary, photographic, and cinematographic representations by such authors as Carlos Fuentes, Juan Rulfo, Nacho López, and Fernando del Paso, mediate between the realm of “compulsory visibility” of a modernizing Mexican state and its shadowy byproducts. The first is embodied by the discourses of transparency and hygiene of modern architecture in the Mario Pani’s Nonoalco-Tlatelolco housing complex. The second is the spectral social body inhabiting the hub of the national railroad network at Tlatelolco—that is, self-constructed settlements and tenements of the migrant underclasses, overlooked by the State and eventually displaced by the modernization projects. This blindness and exclusionary practice of the modern technocratic administration is also manifest in the highly managed character of the Plaza de las Tres Culturas erected on the Tlatelolco site, demonstrating the limited scope of de facto citizenship in Mexico. At the same time, the opacity of the site tests the limits of history writing in general.

This chapter discusses the life and legend of two train robbers active in Alabama in the 1890s – Railroad Bill and Rube Burrow. While there is a tendency to see train robbers as embodiments of resistance to capitalism, this chapter argues that it is more useful to see these men as personification of the dangers of capitalism. In their train robbing careers, Rube Burrow and Railroad Bill both exploited the increasing systemization, expansion, connectivity, and circulation of the southern railroad network. The crimes of these men touched off panicky reactions that revealed southerners anxieties about the railroad itself. In the end, these anxieties were obscured by the mythmaking that occurred after their violent deaths. Railroad Bill faded into legend as the subject of a folk song that stretched the truth about his deeds and popular memory and the media conflated Rube Burrow’s legend with that of Jesse James and sought to portray him as an anti-capitalist and neo-confederate avenger.

To reduce the cost and time of transport due to the different track gauges(narrow, standard, broad) in the Eurasian railroad network such as TKR(Trans-Korea Railway), TCR(Trans-China Railway) and TSR(Trans-Siberia Railway), it is very necessary to develop and adapt the gauge-adjustable wheelsets system. The freight trains’ with gauge-adjustable system could operate on the different track gauges in the transcontinental railway. Therefore, to assure the safety of the newly developed gauge-adjustment wheelsets system, it is essential to evaluate integrity of locking parts in the system by using fatigue analysis. In this study, it was performed that contact stress analysis of locking parts by using FEM(Finite Element Method) in the case both the gauge changeover operation and freight trains' service in the curved track, respectively. Besides, to consider the variation of fatigue data, the crack initiation life was statistically evaluated.
