Here's a "what's that thing" that surprised me and it's a real curiosity: a zoomorphic track inspector's draisine from about 1845. I can't quite work out how you balance it on rails, maybe you always keep your feet on the ground? Why didn't they put another wheel on the other track? Wolf or dragon? So many questions.
The word "draisine" traces back to Karl Drais, the German inventor whose 1817 pedestrian "Laufmaschine" — pushed along by foot, with no pedals — became an unexpected fashion craze in Paris and London under the name vélocipède or dandy horse. The fad faded within a few years, but the name stuck.
The rail version came later and separately: in 1837, Franz Aloys Bernard in Vienna adapted the draisienne concept to run on rails. Both the road and rail versions honor Drais's name, even though the rail draisine was really a different invention built for a different purpose — track inspection and maintenance rather than recreation. In French all track inspection and maintenance rail vehicles are still called draisines.
