Chris,
You're absolutely right. Ben Fleskes figured this out early on. The driver
wheel assembaly is pinned on both ends. The back is pinned to the rear power
truck that pivots and translates up and down and the front to a "tounge" that
pivots and translates up and down. The tounge is tiled and slides into a tiled
void in the front "super truck" to allow for expansion/contraction around
curves.
I call it a super truck because compared to a regular truck its huge. This
allows for details that if were body monted would be obstructing the front
truck. The bogie plate is attached a full brick above the wheels sets and it
is 8x14 studs in size including the cow catcher.
The pic is a bit fuzzy but I posted it up on BrickShelf.
