other question that people have asked is like well what happens if I load my save file and the trains are colliding and the answer to that is actually similar thing like when you when you re-rail your trains sometimes they'll re-rail and be colliding because their last state was a collision state right but when you re-rail trains and they're colliding they actually just won't have collision on them until you drive them so, the same kind of thing will either happen on load where they won't have collision if they're if they're colliding or they'll derail but then you can re-rail them again they won't have collision and then you can dismantle them and rebuild them to where you need them to go so like if you have trains you know colliding on load that will be like just a minor headache but but you can solve it it should be it should be no problem okay so that is all
