One of my biggest problems with TSW CSX Heavy Haul is the obvious lack of basic research of the locomotive. This becomes very apparent when listening to the horns on the locomotive as the are (for the most part) are incorrect. All it takes to realize the horns are wrong is to just to watch a few youtube videos. I would also like some more research done on the throttle system as it is obviously not true to life. Otherwise the game is fun and enjoyable. And the new first person mode adds a lot to a game like this.
