Collins, Marjory, "Baltimore, Maryland. Workers boarding a trackless trolley at four p.m. Trackless trolleys are more economical than buses to run because they require no gas; but do use tires. They are run by electric power in wires above the street and can be manipulated from one side of the street to the other," April 1943. Courtesy of Library of Congress
