I'm nearly finished with my HE 4-6-0, and thought I'd share some pics. It uses 3
pair of the BBB regular drive wheels, non are blind drive wheels. And it had a
drive rods spannig all tree wheel sets.
After experimenting I had several ideas to get 3 pairs to work, all of which
were also mentioned here by others. But the only ones that would allow me to
runn drive rods to all 3 sets was either make blind drivers, or design it so
the inside center drive wheel could be pushed in 1/2 stud while on curves. I
choose the later, as I wanted the wheels to match each other. This solution only
works of you are useing 6 stud center spacing, with 7 stud the front and back
set bind to much and tend to derail.
I used technic bricks for the wheel base, and a thin technic beam to space out
the center wheels. The wheels are mounted on 2 stud axels with a small spring in
the center between them.

If there is a beter way to build th edrive rods, I would love to here of it. I
have a limeted technic collection, but plan to swap out the U-joints with non
locking Technic Toggle Joints.
I still need to add a bit of detailing, and build the tender. And after that
convert the coach cars to 7 stud and 1 brick taller.
