This edition has the same objective as the preceding three editions: to furnish accurate information for building realistic bridges on model railroads.
The number of photographs have been increased from 3 to 37, 225 of the line drawings are either new or redrawn. Cross references are now by page number making them far easier to locate. All plans are taken from prototype drawings or from measurements made of prototype bridges.
Chapter topics include the purpose and engineering of bridges, types of bridges, selection of bridge type, culverts, abutments, piers, shoes, pedestals and trestles. This is by far the best book on prototype railroad bridges and trestles for the model railroader.
Carstens Publications, softcover, 156 pages, standard portrait book 8 x 10 in., B&W photographs and illustrations.
