This book is an excellent reference for anyone planning to add trackside industries to his or her model railroad. The book presents information about typical industries that can found near railroads. Details of the operations, procedures, buildings and other structures used by these industries are included. Even though this book is a very good source of information about trackside industries, it does not contain information on how models of these industries can actually be constructed. So, if you intend to add industries to your model railroad, you may find that a book on constructing models of industrial type buildings will also be very helpful.
