"Dust Devil" Windmill Railcar (front)
Although windmill-powered vessels were not known for their agility, smaller evolutions of the concept were indeed quite fast. The Dust Devil was a one-manned vehicle with a propeller mounted as low as possible above the chassis and geared for maximum power. The low windmill allowed this railcar to reach great speeds without any fear of capsizing, but it also denied much cargo room and forced the pilot to be cautious of the spinning blades behind him. Dust Devils were used primarily for track inspection and maintenance, but also became popular rail racers as most coal-powered amusements had been banned.
