I probably should stick to things I can understand better. But still, its a nice
calculation!

This is one thing I pondered about too. With the way they are displayed on his
table, it would seem that they were display models. Yet the motors suggest
otherwise. I'm not sure how he'd do curves either. Perhaps the 1 x 1 round - 1 x
3 style construction? although the SNOTed technic beams that make the track
itself, again, suggest otherwise.

I was thinking about the weight of your models too. It seems train motors can
handle only so much, and then they burn out.

I second that.
