These 60'-7", automobile box cars were built by PS (lot 9146A) as above. They featured double 8' Youngstown sliding doors, H-40 cushioned underframes and capacity as above.
It is unclear the purpose of the fragmented nature of the numbering of these cars, but I suspect it has something to do with their probable assignment to auto parts service and the associated pools.
