Auxiliary Locomotives of the Pacific Northwest
Steam dummy pulling a horsedrawn streetcar in Albany, Oregon, circa 1900.
The horsedrawn car of the 1890s was replaced with a steam dummy (pulling the same car) about the turn of the century. Then progress brought the small steam engine pulling one railroad passenger car. And this was followed by an electric car.
Steam dummys are awesome because they are tantamount to homebrew steam locomotive-powered trolleys - no two look alike. This is in Albany. Note the dirt roads. Operators and/or patrons look a bit rough and tumble.Culp, Edwin. Stations West, the Story of the Oregon Railways (1972). p. 226.
