I just toured the Roundhouse at Southern's Spencer Shops last week. It is in good shape and about half full of some good old pig iron and woodside cabooses.
It happened to be School Kids Day and they were operating the Turntable for rides and for viewing *FP-7 6133. The FP-7 was coupled to 5 coaches and loaded with Kids for the standard trip[s] around the grounds.
