If I remember correctly the 6 cars (X950's) were steel side dump gons that were on the roster prior to shutdown but were never delivered to the CATS. The 1967 list that went with the transfer has various problems in that the final transfer list looks nothing like it in some areas and other cars have been received since. There is an official list that we made a few years ago but I can't remember who published it. It was in 2110 or2002.
