It designed and constructed interurban cars, streetcars (trams) and (in smaller scale) buses.

Its chief engineer Thomas Elliot designed the curved-side car, a lightweight model that used curved steel plates (not conventional flat steel plates) in body construction.

[1] In 1929, the company designed new lightweight partially aluminum low profile high-speed coaches for the electrified Cincinnati and Lake Erie Railroad interurban that operated between Cincinnati, Dayton, and Toledo.

These interurban cars, whose open country speed could reach 90 mph (140 km/h), were a forerunner of today's high-speed trains.

Both the carbodies and new design small wheel low riding trucks were well adapted for high-speed running on light rail rough track.
