Thanks Tom. Motor does look similar to the steamer motors just a bit smaller. I have a few DC transformers from my HO days. Might try it.
Broke, you might have a DC transformer from your N scale endeavor. Try it on your steamers and see if you can get some slower running. I don't know where the start voltage is but got to be better than 7 volts. I know AF made their transformers start at 7 volts because that is what it takes to change reverse unit. But it is too high of a start voltage for me.
