Book Description
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. In this paperback rerelease of the successful 2003 title, the otherwise-arcane world of railroad signaling is explained in concise language and brought to life with nearly 200 fantastic photographs that depict signaling history and all aspects of modern operations. Author and photographer Brian Solomon brings his wealth of knowledge and photographic talent to a subject that has not often been tackled in book form, yet is integral to the American railroad experience.

Book Description
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.
