The Invention of the Track Circuit

The book comes from the Signal Section of the American Railway Association, New York, 1922, and presents the history of Dr. William Robinson's invention of the track circuit. The preface says that, believing no more fitting memorial can be prepared in honor of Dr. William Robinson, the committee reproduces the salient points relating to his great achievement as written and published by himself in 1906. The preface says Part II is devoted to W. A. Baldwin, formerly General Superintendent of the Pennsylvania Railroad.

The text says an installation was made at Kinzua, Pa., and after a little experimenting was soon in perfect working order. The text says Mr. Robinson, who aimed to be the most severe critic of his own work, entered systematically into a deeper study of the system from the standpoint of a railroad man. The text says the original name of the Robinson Company was The Union Electric Signal Company, which Robinson organized and owned in 1878.
