The elusive rail cars were sold as part of the work train. Original rail loads were never assembled as track so there are no crimp marks from the cross ties. There is some question whether there should be nine or twelve rails. I suspect twelve is probably correct.

Some time ago a fellow collector came up with a set that had a clamp for these cars. The clamp was made from a track crosstie. It was punched to fit down over the stakes much like the lumber load clamp.
