There is a sliding joint between the forward pivot in front of the drive
wheels that translates forward and back relative to the leading truck. Thus,
when the train goes around curves, the joint slides out, and then comes back
together when it enters the straights. This joint is two studs wide and about
two plates thick. It fits in an opening two studs wide and about four plates
tall. This allows the drive wheels to float up and down as the train goes
over bumps and changes in incline.
Or put another way, without the body on the wheels, the leading truck can be
slid completely away from the rest of the wheels.
Does that answer the question? I do not have a picture that shows the units
apart from one another, so it is difficult to tell.
