Anyone used these to power a loco?

Kevin, I was wondering the same things... enough power to pull a twenty car train, and how noisy. On the noise issue, seems they would be pretty quiet. No external drive shafts and univesal joints and such. On the surface, it seems like a great idea. But the motor in there must be pretty tiny, which leads to the "how much power" question.

Still, I am salivating at the prospect of having tons of room in a CF7 shell!

...and no flywheels. Do you still have all those model railroader back issues? I remember an early 1990s article about someone building an SW1 from two PDTs. A 20 car train may be pushing it - but 10 cars on level ground sounds reasonable. Perhaps send an email to NWSL and see what they say.
