To determine the employment characteristics of workers covered jointly by old-age and survivors insurance and the railroad retirement program, a sample of the work histories from the Bureau of Old-Age and Survivors Insurance and the Railroad Retirement Board has been analyzed. In the analysis the hypothesis has been developed that, as time progresses, virtually all railroad workers will at some...

This paper addresses the determinants of three types of railroad related fatalities: trespasser fatalities, those at grade crossings, and those involving passengers and employees. Of particular interest are the effects of railroad deregulation (the Staggers Act) on railroad related fatalities. Models are developed using specification error analysis and seemingly unrelated regression. Deregulati...

This is a review of walking tasks in the railroad environment, and the injuries that result from slips, trips, falls, or other acute or even non-traumatic exposures. The lack of federal regulations for railroad walkways has led several states to develop and enforce their own regulations. Support from the research literature for such regulations has come from biomechanical studies of the effects...

The reactive plan of the Madura railway line received a favorable response from four regents in Madura. As can improve economic development and facilitate human goods movements easily. In its development, potential for island needs to be noticed terms both economy infrastructure. on itself is still impressed as not well developed compared city Surabaya which directly adjacent Notable condition ...

This study is aimed at developing automated methods to recognize railroad infrastructure from 3D LIDAR data. Railroad infrastructure includes rail tracks, contact cables, catenary cables, return current cables, masts, and cantilevers. The LIDAR dataset used in this study is acquired by placing an Optech Lynx mobile mapping system on a railcar, operating at 125 km/h. The acquired dataset covers ...

While the United States government concentrates more of its political and financial resources on fighting terrorism, the continuing decay of older cities and industrial suburbs has fallen far down on the national political priority agenda. An exception is the redevelopment of so-called brownfields, which are abandoned, idled, or underutilized factories, railroad yards, bus stations, garages, el...

This paper investigates the relationship between railroad bond defaults and nancial outcomes in the National Banking System during the Panic of 1873. Contemporary accounts and anecdotal evidence indicate the importance of a boom and bust in the railroad industry to the onset of the panic. I use comprehensive balance sheet data for national banks before and after the panic, along with detailed G...

The seismic failure behavior of railroad ballasts in response to earthquakes was analyzed using Discontinuous Deformation Analysis.Several sinusoidal waves with different frequencies and accelerations were inputted into the discontinuous numerical model of a railroad ballast ,which consists of an assemblage of polygonal crushed stones,rails,sleepers and a roadbed .The dependencies of railroad f...
