Description

Handsomely done compilation of information on oil-fired railroad signal lamps. This book covers their use from the 1870s on as they grew into a large industry by the turn of the century and then further expanded as trolley and interurbans grew. The business peaked in the 1920s when electric lamps began to replace them. This volume covers 17 companies and their products in detail as well as those made in railroad shops. With appendices on railroad signal glass, founts, burners and chimneys, and railroad issued signal lamp drawings. Illustrated throughout with black and white photos and drawings. 368 pages. Very scarce.
