The AC4400CW and the C40-8W don’t have near enough chugging sound to their engine to how they would actually sound in real life. They have chug in the game but it’s incredibly soft and the sound of the turbo way overpowers it. This is not at all what it sounds like in real life. They also need to have a “whoop” sound when the air compressor turns on.
I think this page could help ya out with that: https://www.store.searchlight-simulations.com/enhancements-index-1
Train Simulator 20XX ain't on console. Train Sim World and Train Sim World 2 however, are on console. So no. Searchlight Simulations' stuff isn't available on consoles, as nice as it would if they were. Anyways, if this is a TSW2 suggestion, it's best to go over to that section of the forums. These here are the Train Sim Classic forums.
I know it's unrelated, but if you don't have SS's 7FDL pack, you are missing out. It is so good. There are a couple of issues (I've only used the C40), but it's still worth it. Plus, it's free!
