Suggestions for Locomotives?

[Brakie]

Another look through the Trackside Guide shows a lot of SW1500 and some SW1200. Most of them are industrial, restricted to plant use, but a lot of the short lines have a single SW mixed in with the GP and SD. (Ontario listings only)

Then you have urban industrial switching roads that uses end cab switchers from EMD and yes, some Alco end cab switchers. By far various types of Geeps is favored by short lines while some regionals favors GP38s/38-2s/40 and 40-2s with 6 axle SD units. Some terminal switching roads uses EMD end cab switchers, Geeps and SD units.
