This is interesting information, thanks TJ. I must say that I got the visual
impression that the buggy motors seemed to have more than a mere 2 - 3 times
more shaft power output than the gear motors.

Yes, I did too. Judging from the performance of the RC car, you'd think the
motors would be equivalent to perhaps 8, or more, of the geared 9V motors.
The buggy can really zip along!

There was one other thing about my test. When the 9252 motor stalled, the
green LED on the train controller dimmed significantly. I wonder if it was
able to provide adequate current. Surely so! If not, then my torque results
could be low.

The limitation on the train controller is the wall wart - not the controller
itself. There was discussion on this in .trains a while back. Someone built
a tranformer box with about 3A output IIRC, and ran several trains with it
through an un-modified controller. There was someone else that actually
modified the controller rectifier with higher rated diodes etc, and added a
fan, but that's probably only necessary for prolonged use.
