Thanks for the advice, Lutz. Unfortunately, I don't have any gears handy, but I did find an inexpensive Canon EN-22 on eBay: http://www.ebay.com/itm/301797565577?_tr...EBIDX%3AIT
It's the 5-pole version of the DN-22 (3-pole), same size and body. I replaced the motor and that solved the problem. I found some information that ohming out the windings will let one know if it is a 24v or 12v motor. The DN-22 windings are about 60 ohms; hence, the DN-22 I had is a 24v motor, so caveat emptor when buying motors on eBay.
The Big Boy ran well on my layout, pulling all the cars I had available, and handled the grades on my friend's layout with ease. I'm going to have to tweak the decoder settings to get it run more to my liking, slow and steady. For a 40-year-old, $30 Shelf Queen, it runs pretty well. I don't need a Big Boy and it doesn't really fit my layout, but I've always wanted one, if that makes any sense, so this was a an inexpensive way to scratch that itch.
