A. Wells - Thanks for the props.
Mowingman - Thanks again for the info, I will check out those companies, many of which are new to me. A pair of the Cranemasters cranes would be nice in 1/48 or 1/50th. It looks like a pair can lift a locomotive. I think it takes (4) large sidebooms to do the same.
A few more photos from the same year, the CSX MOW mother-load at ACCA yard, Richmond.
