Eric,
If the pivot point on you model was moved to the top then you train would act
like a Talgo train. Instead of the top moving inward, the bottom would swing
out. The swing of the cars has to be translated to a bending of the joint
between the cars. But what I am thinking about will not allow the trains to go
through an "S" because the cars would not be able to pivot in different
directions....ah never mind I have no idea what I am talking about.
Chris
PS. Eric I love your site. Not only are the models and ideas great it is a very
well done web site. The search light effect...the spot lights...very nice!
