AHM Alco S2 Switcher HO Guage

On the box it says this is a GE 1000 hp locomotive but to me it looks like an ALCO S2. An image search agrees with me. Everything matches although I didn't see the bell on the S2 switchers. Note this is a dummy locomotive. On a real train there are usually 2 or more locomotives but 2 powered locomotives do not work well on an model train layout. As a switcher they would often work in pairs.
I collect the railroads that worked in this area which are Southern Pacific, Union Pacific and Santa Fe.
PS circa 1970.
