This fascinating, well-illustrated and informative book presents a straightforward guide to points, signals and level crossings and provides all the information that railway modellers need in order to get the trains on their layouts moving effectively. The history of semaphore and colour light signals is outlined and the implications for modellers is clearly explained. A variety of different types of points, signals and level crossings is then illustrated with detailed instructions describing how to make them work. Simple, tried and tested mechanical and electrical methods used by modellers are explained together with modern electronic approaches, which are described in a way that enables them to be easily understood. The reader is taken step-by-step through various projects, and clear diagrams and photographs are provided throughout, including wiring diagrams for frogs, signals and level crossings. Written by an electronic engineer, this book contains invaluable information gained in a lifetime's experience of railway modelling and will help both the new and the experienced railway modeller to understand electronic and electrical concepts and bring their model railways to life. Fully illustrated with 156 colour diagrams and colour photographs.A Mechanical, Electrical and Electronic Guide for Railway Modellers Clive Heathcote, Annie Anderston.
