You talk about the trucks sliding forward and backwards. It seems to me that
the body would hinder this from happening due to the fact that it connects to
the the front and rear trucks via two stationary pins. Since the body doesn't
stretch what lets this occur? On the location of the body where it attaches to
the trucks did you use those white spring loaded pieces similiar to the ones
found on the crossing gates in 4559?
