Hopefully someone from DTG can answer this, hopefully Matt. Are the railroad companies that are being represented in the game able to provide sounds for the team?
No is the answer to that. They will mic up a train if a company agrees to let them, but some won't give access to the actual train hence sometimes third party or 'close enough' sounds are used with varying success. That said a lot of the complaints seem to be about the mixing and Unreal Audio engine than the source audio.
