They had outriggers and just lifted them up enough to move back and forth. They had two of those working at the wreck at Billy goat cut. I worked that one till I dropped. Phillipsburg had at least one and many more derailments.
I was looking at Bill's photo of the Memphis MW #33 caboose - what color is the rear door and the window framing? Could obviously be black - but maybe some other dark shade?
