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.
