| | | | | 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 (...) (25 years ago, 22-Mar-99, to lugnet.trains)
