Given the wide variety of rolling stock in the real world, I find that the current bogie/truck system might be a bit limiting on just what rolling stock can be modeled. I propose adding span bolsters in as an additional option for bogies/trucks. This would allow larger pieces of rolling stock such as large capacity freight cars, Schnabel Cars, and railroad guns to exist in the mod without relegating their trucks to a single solid mass which would appear quite off while negotiating curves. This feature also probably needs to be added for locomotives as well especially diesels/electrics where units such as the Baldwin Centipede and the PRR GG1 exist with articulating frames. I'm not sure if this will all fit under the new animations feature that's being worked on, but I hope that we can get more articulation/bogie options for engines and rolling stock soon.

Thank you for your time.
