While we have been talking about grandiose highly technical designs I made couple of simple little models. The new model is a simple coach which resembles the little coaches LEGO produced in the '80's. The other thing I finally decides to do was put (...) (26 years ago, 24-Mar-99, to lugnet.trains)

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

I think you are right, the "steering" of the single wheelset must be linked to the swinging of the car. The weight of the cars would hold the wheelset straight, but as the train goes into the curve the swinging action would cause the wheelset to (...) (26 years ago, 22-Mar-99, to lugnet.trains)

What makes the Talgo train a challenging model is not only the common *single* wheelset between cars, but that the cars pivot inward when rounding curves to allow a higher speed and more comfortable ride for the passengers. I've made cars that will (...) (26 years ago, 21-Mar-99, to lugnet.trains)
