Paperback. Etat : New. Print on Demand. This book takes an introductory look into the fundamentals of automatic railway signalling and track circuits for railways. The author, an expert on the subject, takes an extensive look at the equipment and methods used in both steam and electric railways. Track circuitry and its components are examined, as are different types of power and the importance of rail bonding and insulating rail joints. Different signalling systems are explained and illustrated, including details on signal locations, normal danger, normal clear, overlaps and various other aspects of signalling systems and track circuits. The book concludes with a look at light signals. Both the author and the editor have put together a highly informative and technical book, accessible to a reader familiar with electrical matters and railways but new to signalling.
