Not exactly. SD9's were not regularly assigned as yard units at Roseville, only being used as such when other suitable units were unavailable.

Regarding SD7's, SP reclassified them from DF ("Diesel Freight") to ES ("EMD Switcher") in 1965, although they had been commonly used in yard service at various locations for many years prior to that.

In Roseville Yard, they were nearly always used only for flat switching since none the the SD7's assigned there were equipped with Hump Controls (although they could be used as trailing units if necessary).

SD7's assigned to Taylor Yard in Los Angeles were assigned to flat switching and as hump power, with selected units being equipped with Hump Controls, in addition to being used on outside yard jobs, transfer runs, haulers and locals.

UP classifies its de-turboed SD40-2's as SD38-2's.
