early Toronto Transit Commission experimental trolley bus

A painting titled "Trolley on Mt Pleasant Toronto c. 1922" by artist Ken Kirsch which depicts an experimental trolley bus which operated between 1922 and 1925.

Operating on the Mount Pleasant route, the 1.9-km line served as a cost-effective alternative to laying streetcar tracks in lower-density neighborhoods. The experiment was so successful that ridership outgrew the small buses, leading the TTC to replace them with streetcars in 1925. 

There were 4 buses numbered 20 through 23 which had J.G. Brill bodies on Packard Motor Car Company frames, and Westinghouse electric motors. Tires were solid rubber (not pneumatic). They had seats for 29 passengers.
