The trick is to cut down the rolling resistance by cutting down the
number of bogies/wheel sets. Instead of each car having two sets of
wheels, two cars are connected to one sets of wheels. I regularly see
flat bed cars that have wheels arranged like this.

   ____car____  ____car____  ____car____
x--x         x--x         x--x         x--x

instead of the standard

____car____  ____car____  ____car____
x-x     x-x  x-x     x-x  x-x     x-x

Anyone working on a reduced wheel set design? There are certainly some
interesting technical issues invovled. Anyway, just trying to spark more
discussion.

Been there, done that. An artic was the very first thing I tried.

I can't find the pics anymore but it was pretty fragile. It used 2x2
turntables for the pivots.

I did a 5 unit double stack just before I left CO. See:
http://my.voyager.net/lar/containers.html and go to the bottom.

That uses technic 2x2 tile with center technic pin for the pivots. Much
sturdier.

Zonker Harris did a Thrall-ish double stack too, also using 2x2
turntables.
