Right, like O-Gauge trains have. This is the configuration I'm suggesting
when I say this. For those who aren't familiar with O-gauge, this means the
motor would attach to the body with the pilot and trailing trucks swinging
out. Actually, I think this system is used in all the other scales.

Agreed, this can be accomplished with the same config as mentioned above.
And those pulley wheels just don't scream "highballer" to me. They're
barely bigger than the train wheels (well, the model team ones are w/ tires,
but then the valve gear isn't at the edge of the driver).
James or Robin S., could you give a link to the Hogwart's Express moc?
Sounds neat.

Yeah, I hadn't thought about the pickups, but those would definitely be
awesome. No more putting motors in the tender, and switchers and tank
engines would be MUCH easier to build.

umm...what? I'm afraid I'm not quite sure what a coupling rod boss is. I'm
talking about the side rods when I refer to valve gear linkages.

Hmm...hadn't thought about dk. red. What kind of engine uses dk. red
(question, not sarcasm)?
