Your Guide to Railway Signals

This is a railroad industry general reference textbook. This is not a model railroad signaling guide. This book is intended for use by railroad industry professionals but rail enthusiasts who want more information about railroad signalling by railroads in North America will find this interesting. Familiarity with electrical terms will be helpful.This is the book for you if you strive for railway signaling knowledge. Your Guide to Railway Signals is an excellent guide for training signal personnel especially railway cross-function managers, supervisors, and support personnel. Signal personnel and management can use this book as an information packed off-the-shelf reference guide. High-quality graphics and diagrams have been used throughout. Complies with all standards and commonly used practices.Includes chapters on Track Circuits, Basic Crossings, Gate Crossings, Microprocessor-Based Crossings, Switch Circuit Controller (SCC) and Electric Locks, Switch Machines, Relay-Based and Processor-Based CTC, and Testing Locking Circuits. Contents: Definitions (railroad and electrical terminology), pp. 5—52 Introduction to Signalling (explanation of terms such as derails, interlocking limits, etc.), pp. 53—86 Track Circuits (coded DC track circuits AC-DC track circuits, ballast resistance, etc.), pp. 87—112 Basic Crossings (lighting, bell, inspection frequency, etc.), pp. 113—150 Gate Crossings (gate mechanism, control circuits, mechanical), pp. 151—186 Microprocessor-Based Crossings (track and AC signals, overlapping crossings, relay vs. solid state, etc.) , pp. 187—216 Switch Circuit Controller (SCC) and Electric Locks (physical description, wiring methods, electric switch lock), pp. 217—236 Switch Machines (mechanical features, operation, cross-overs, etc.), pp. 237—274 Centralized Traffic Control (CTC) - Relay Based, pp. 275—300 Centralized Traffic Control (CTC) - Processor Based, pp. 301—336 Testing Locking Circuits (approach locking, traffic locking, route locking, etc), pp. 337—360 Index, pp. 361—370.Simmons-Boardman, softcover, 370 pages, standard portrait format 11 x 8.5 in B&W illustrations.
