Book Description
A look back at Shrewsbury's railway infrastructure and train services as they were between 1987 and 1994 from a 2014 perspective, focussing particularly on the six mechanical signalboxes then operating in the town and the predominant semaphore signalling they controlled - including the UK's (and now also the world's) largest: Severn Bridge Junction with its 180-lever frame. In these last few years of nationalisation on the UK's railways, before fragmentation and tighter cost controls brought on by privatisation took effect, first generation diesel motive power is seen giving way to newer types of traction, while locomotive-hauled passenger trains are falling out of favour and being replaced by more economical railcar services. Also shown are the much-lamented regular Intercity trains to London, lost freight and postal traffic, and the summer Saturday holiday trains that used to pass through the town on their way to the Cambrian coast. Written by a British heritage railway signalman and former resident of Shrewsbury, this book focusses on just a small part of the UK's ever-evolving rail network but witnesses the effect of the changing times on its operations, and the outcome of both modernisation and rationalisation as mechanical signalling technology is adapted for or superseded by the needs of the late 20th Century railway and beyond.

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.
