The Delaware Coach Company was originally incorporated as the Wilmington & Philadelphia Traction Company on June 25, 1910, and operated an electric street railway line from Wilmington, Delaware, to Chester, Pennsylvania, and to Philadelphia. Throughout the early twentieth century, the company purchased stock in and leased numerous electric railway, transportation, and utilities companies in the Wilmington and Chester areas. In 1941, it changed its name to the Delaware Coach Company as trackless trolleys and buses replaced electric streetcars. Included are official documents and correspondence; personnel and financial records; public relations files; land deeds; legislation; labor agreements and contracts; equipment, fare, and route policies; ordinances; minute books, and other miscellaneous material created by Delaware Coach and its predecessor electric streetcar companies.
