Excerpt from Railway Signaling in Theory and Practice In the ensuing pages, it has not been my intention to treat the subject of railway signaling as practiced in America in anything but an elementary way. Even the elements are not always readily grasped by persons who have not had some practical railway experience, and are at least somewhat familiar with the ordinary methods pursued in constructing tracks, moving trains and in the nomenclature used by those whose daily life is spent in actual railway operation. My object has been to supply a want which I myself felt sorely at the beginning of my career as a Signal Engineer - that of an elementary text book bearing on the subject. The matter was originally compiled with a view to publishing it serially, and indeed nearly one-half of it has already appeared in that way. Although I have taken as much time as it was possible for me to spare from a busy life to arrange and revise the matter in proper form for its present appearance, I cannot but feel that I may have left a great deal yet to be done. I can only say that I have tried to do my best and that I hope the book will be well enough received to give me a chance to make any revisions which may appear advisable in a later edition. I have taken the liberty fully to express my own opinions where I have thought necessary, and have always endeavored to impress on the reader's mind that they were such so that he could take them for what they are worth. After more than eighteen years spent in the operat ing department of a large railroad, and nearly seven years as its Signal Engineer, I cannot but feel that these opinions must be worth something now if they ever will be. The reader must judge for himself. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Excerpt from Railway Signal Engineering (Mechanical) The signalling of railways has developed rapidly, more especially during comparatively recent years, until it is now one of the most important branches of the Engineering Department. On its efficiency depends to a large extent the safety of the travelling public. That the Board of Trade recognises this fact is evidenced by the strict supervision which it exercises over the signalling of railways and the careful inspection made of new signalling installations. The demand of the public for greater facilities both for travelling and for merchandise, involving a greater density of traffic, has added to the complexity of railway working, while the modern necessity for speed and for heavier and longer trains has still further increased the difficulties which beset the signal engineer in providing immunity from accident. The advance in signal engineering practice has, however, been commensurate with the advance of railways. The efficiency of the system adopted on British railways may be gauged by the few accidents which occur compared with the enormous number of train movements, and of these accidents the majority are due not so much to any deficiency in'the system as to the personal equation, which unfortunately cannot be entirely eliminated.

Excerpt from Railroad Signaling in All Its Branches We have purposely limited the scope of this book to the extent of dealing only with detail parts, in order to facilitate the ordering of a complete device, or any part thereof. It is our intention to issue a new general catalogue, having reference more especially to the science and art of railroad Signaling, and showing by diagram and explanation what we consider the best practice in connection with the various branches of the art.

Before the widespread popularity of automobiles, buses, and trucks, freight and passenger trains bound the nation together. The Station Agent and the American Railroad Experience explores the role of local frontline workers that kept the country's vast rail network running. Virtually every community with a railroad connection had a depot and an agent. These men and occasionally women became the official representatives of their companies and were highly respected. They met the public when they sold tickets, planned travel itineraries, and reported freight and express shipments. Additionally, their first-hand knowledge of Morse code made them the most informed in town. But as times changed, so did the role of, and the need for, the station agent. Beautifully illustrated with dozens of vintage photographs, The Station Agent and the American Railroad Experience, brings back to life the day-to-day experience of the station agent and captures the evolution of railroad operations as technology advanced.

Excerpt from American Practice in Block Signaling: With Descriptions and Drawings of the Different Systems in Use on Railroads in the United States There are practically two systems of block signaling, of which we may call the first the simple block system. Assuming that every railroad is properly supplied with telegraph offices, this may be said to be merely a code of rules by which the attendant at a given station exhibits a signal to hold all trains moving in a certain direction until he receives word by electrical communication that the last preceding [train has reached another station and gone out of the section of track intended to be protected. This is an absolute block system. When the regulations permit a second train to be sent over the road before the first one has gone out of the block section, but under instructions to run slowly, the term permissive blocking is used.

This book constitutes the refereed proceedings of the 7th International Joint Conference CAAP/FASE on Theory and Practice of Software Development (TAPSOFT'97), held in Lille, France, in April 1997. The volume is organized in three parts: The first presents invited contributions, the second is devoted to trees in algebra in programming (CAAP) and the third to formal approaches in software engineering (FASE). The 30 revised full papers presented in the CAAP section were selected from 77 submissions; the 23 revised full papers presented in the FASE section were selected from 79 submissions.
