From the 1830s to today, the railroad industry has developed myriad complex mechanisms to help keep North America’s railroad rights-of-ways safe, efficient, and relatively accident-free.

The Bakerloo is the dull brown line on London's iconic tube map. It doesn't have the multiple branches of the Northern or District Lines, the loops of the Piccadilly or the Central, or the puzzling shape of the non-circular Circle. But its nondescript appearance belies a history encompassing fraud in the boardroom and drama in the courtroom for a line first conceived by sports enthusiasts and finished by Chicago gangsters. With over 120 photographs, this book provides a history of its development from obtaining Parliamentary permission and raising finance through to geology and construction techniques. It details its operation including rolling stock, signalling, stations and signage from the beginning to the current day. The impact of the two World Wars is revealed and it remembers some of the accidents and tragedies that befell the line. Finally, the book describes its evolution up to the present day and beyond.

The Oxford History of the United States is by far the most respected multi-volume history of our nation. In this Pulitzer prize-winning, critically acclaimed addition to the series, historian Daniel Walker Howe illuminates the period from the battle of New Orleans to the end of the Mexican-American War, an era when the United States expanded to the Pacific and won control over the richest part of the North American continent. A panoramic narrative, What Hath God Wrought portrays revolutionary improvements in transportation and communications that accelerated the extension of the American empire. Railroads, canals, newspapers, and the telegraph dramatically lowered travel times and spurred the spread of information. These innovations prompted the emergence of mass political parties and stimulated America's economic development from an overwhelmingly rural country to a diversified economy in which commerce and industry took their place alongside agriculture. In his story, the author weaves together political and military events with social, economic, and cultural history. Howe examines the rise of Andrew Jackson and his Democratic party, but contends that John Quincy Adams and other Whigs--advocates of public education and economic integration, defenders of the rights of Indians, women, and African-Americans--were the true prophets of America's future. In addition, Howe reveals the power of religion to shape many aspects of American life during this period, including slavery and antislavery, women's rights and other reform movements, politics, education, and literature. Howe's story of American expansion culminates in the bitterly controversial but brilliantly executed war waged against Mexico to gain California and Texas for the United States.
