Ex-CSD #M124.001 in the CD Muzeum, Luzna u Rakovnika, Bohemia (CZ), 2010

This is another unit that I can't get info on right now. It's M designation would indicate a DMU, a gas-electric doodlebug, or something similar, but it's actually a "steam motor car" or "steam carriage," built in 1903 by Ringhoffer, which would make it of Austrian kkStB heritage, originally carrying the number 1001. Since kkStB's Czech stock was transferred to CSD eventually, that's how it got its CSD number. In actuality, it was one of two such steam motor cars intended for use on the Czech Northern Railway, which proved to be too steep for them, and kkStB ended up with them after they were rejected. Both were originally called "Komarek" steam motor cars, and in contrast to the originally rural setting that they were supposed to operate in, they ended up in suburban services out of Prague. They were phased out of this service before the end of steam on CSD, though, with #M124.001 ending up in the Narodni Technicky Muzeum as early as 1949. As far as I know, #M124.001 is the only surviving unit now, and the CD Muzeum claim that it is the oldest operating steam vehicle in their collection.
