Mysterious Cog Railway, unknown location (America? Europe?), mid-1950s, English Ektachrome original transparency.
This image presents a mystery; clearly a cog railway (gears on the locomotives and rolling stock connecting to a central gear-track to prevent downhill runaways), but no idea where it is. Photographed by a likely British citizen, as the original film is an English Kodak Ektachrome transparency.
