SP only ever owned 4 of these, although 23 were built, the other examples going to UP, Santa Fe and Southern Rwy. Espee's were delivered with 'Elephant Ears' over the rear radiators, these were a feature to test the Tunnel Motor radiator theory, and were also fitted to some SD45s, later removed. They also came with a brake wheel on the nose, and a matching air duct on the right hand side rear walkway. 7200 and 7201 were delivered as Locotrol Masters, with 7230 and 7231 as Locotrol Receivers or remotes, this equipment was also later removed.
