Hello, I'm an enthusiast of the brilliant series you have provided over the years. I'm a player since Train Simulator 2010 (from 8 years ago). Now I have just bought the steam version of 2018 and I'm slightly disappointed to see the simulator with some sound bugs (some constantly repeating strange sounds (once a second or so) which didn't exist in previous versions) and also misses the loud hissing sounds from the pneumatic system of the brakes. Also the lovely loud squeaking sound of wheels under heavy brake is also lost, or barely noticeable. About the pneumatic hissing sounds, I'm not an expert, so it may probably not be heard on modern locos and trains, so I'm not sure I'm right, but I kind of doubt that all freighter locos (which may not be noise restricted like passenger locos) are build not to make the hissing sounds anymore. The same goes for the squeaking brakes noise that seems absent. Regards, Mav!
