Chicago's First Subway System

This publication provides a brief history of transit and subway developments in general before discussing the development of Chicago's subway, including structure data, information about stations, and signals. The section on Passenger Cars consists of one sentence: "New equipment required – all steel – probable width 9'6" or one foot wider than present cars on elevated lines. The final page discusses "Future Subways (Tentative Only)."
