Book Description
Excerpt from Brake Tests: A Report of a Series of Road Tests of Brakes on Passenger Equipment Cars Made at Absecon, New Jersey, in 1913 1. While the development of brakes for passenger equipment cars has been in progress over a period of many years, it was not until the introduction of heavy steel cars that difficulty was experienced, even with improved air brakes, in making the stops, in service and emergency, which are desirable for medium and high-speed passenger service. It should be possible to make such stops as short, smooth and certain, both in application and release, as was possible with the lighter cars of some years ago. 2. This Bulletin is a record of an extended series of tests to determine the best air brake mechanism and foundation brake gear for our heavier steel passenger equipment cars, which have now been in service some five years and these experiments are remarkable in that they have developed data which indicate that, by a full knowledge of the conditions and proper attention to the component parts of the complete apparatus, very short stops may be made with these cars in trains which weigh close to a thousand tons. 3. There has been a continuous increase in the weight and length of cars, length of train and speeds since the introduction of the quick action triple valve in 1888.

Book Description
"Do not think of the Pennsylvania Railroad as a business enterprise," Forbes magazine informed its readers in May 1936. "Think of it as a nation." At the end of the nineteenth century, the Pennsylvania Railroad was the largest privately owned business corporation in the world. In 1914, the PRR employed more than two hundred thousand people—more than double the number of soldiers in the United States Army. As the self-proclaimed "Standard Railroad of the World," this colossal corporate body underwrote American industrial expansion and shaped the economic, political, and social environment of the United States. In turn, the PRR was fundamentally shaped by the American landscape, adapting to geography as well as shifts in competitive economics and public policy. Albert J. Churella's masterful account, certain to become the authoritative history of the Pennsylvania Railroad, illuminates broad themes in American history, from the development of managerial practices and labor relations to the relationship between business and government to advances in technology and transportation. Churella situates exhaustive archival research on the Pennsylvania Railroad within the social, economic, and technological changes of nineteenth- and twentieth-century America, chronicling the epic history of the PRR intertwined with that of a developing nation. This first volume opens with the development of the Main Line of Public Works, devised by Pennsylvanians in the 1820s to compete with the Erie Canal. Though a public rather than a private enterprise, the Main Line foreshadowed the establishment of the Pennsylvania Railroad in 1846. Over the next decades, as the nation weathered the Civil War, industrial expansion, and labor unrest, the PRR expanded despite competition with rival railroads and disputes with such figures as Andrew Carnegie and John D. Rockefeller. The dawn of the twentieth century brought a measure of stability to the railroad industry, enabling the creation of such architectural monuments as Pennsylvania Station in New York City. The volume closes at the threshold of American involvement in World War I, as the strategies that PRR executives had perfected in previous decades proved less effective at guiding the company through increasingly tumultuous economic and political waters.
