Wheels of Time N Scale 53'-6" General Service Welded Fish Belly Flatcars are based on cars that were late 1950s and later favorites of the lumber and building materials industries. Nearly identical cars were constructed by several builders including Pacific Car & Foundry (P.C. & F.), Marine Industries, Pullman-Standard, Bethlehem Steel and in Western Pacific's own shops. Features of these detailed models include proper weight for great performance loaded or empty, proper ride height, body-mounted knuckle couplers, 33" metal wheels and multiple roadnumbers per roadname.

In 1977 - 1978, Southern Pacific shops rebuilt 66 (1963-64 built) SP Class F-70-12 flatcars with bulkheads like the originally built GBEC SP Class F-70-26 bulkhead flatcars. They were renumbered as SP 507733 - 507799 series and with an added “R” to it’s original class. They were 48’-6” between bulkheads.
