Doodlebugs

Singly. Very rarely, if ever, did they work back-to-back, so don't be tempted.

Some had a trailing passenger car/baggage, PO or combine, and they also hauled a few boxcars from time to time, in a mixed-train way. You can also reverse them out of the scene too, although they were usually turned on a TT or Wye to return to where they came from, if at the end of the line. They were increasingly rare by the late forties/early fifties, as railroads bought Budd railcars, or stopped passenger service all together.
