< Mentor Note -- thread moved to HH from the technical engineering forums, so no HH Template is shown > I have to design similar bogie to one shown above. It's is used on straight rail. I am not sure what kind of construction I should use to connect body to axles. More simple solution - better. Additional information: This bogie (including it self) has to be able to carry 4 tons. Chain gear runs one axle (sprocket). Motor is 0,75kW.
