Thanks a bunch! I am glad you and youre brother are enjoying it so much! As far as the sticky wheel feature, My aim is not to have them handle like the in game trains where you can just hit a corner at 50mph and not worry about derailing. My goal is to keep them as realistic as possible and trains in real life cant just hit sharp corners at high speed without derailing. However, I do think they derail a bit too easily still. So I am working on improving that! The coding you mention is A LOT more easier said then done, but I am working on what I can do to help keep them on the tracks a little bit more
