Consists of minute books from predecessor and early subsidiary companies of Delaware Coach Co. Most are electric streetcar companies in Wilmington and Chester, Pa., that later merged with the Wilmington & Philadelphia Traction Company in 1915. These minute books give insight to the consolidation, merger, and dissolution of several competing street railway companies. Of special note are the minute books of the Wilmington and Great Valley Turnpike Company and the Wilmington and Christiana Turnpike Road, both private turnpike companies that formed before and during the War of 1812 and remained a subsidiary of Delaware Electric Power Co. until the mid-1930s. Early bus lines absorbed by Wilmington & Philadelphia Traction subsidiaries in the mid-1920s are also represented.
