Thanks for your replies! Maybe when I'm done with the full version of this I can trim it down as much as possible so it can be used in BVE. I know nothing about BVE development at this time but I will look into the train model limitations and see what I can do. Can bump or displacement maps be used for BVE? I will update in this thread as I make progress.
Again, if anyone have truck and coupler info please share. It's the only details I'm missing for reference. Don't mean to be such a nerd but I would actually like to know how the trucks (breaking system) interact and relate with the rest of the undercarriage (electrical systems). Always been fascinated with trains.
@Threxx1: Are you saying the trucks used on the R46 are the same for the IRT SMEE fleets?
