Until 1973, CTA's fleet included a large number of electric trolley buses - or "trolley coaches", as they were commonly known at the time.

The Key System had ordered 40 trolley coaches from ACF-Brill in 1945 to convert the East Bay trolley lines.

As late as the 1960s, transit service in Dayton was provided "almost exclusively by trolley coaches".
