I just thought of something. Since the mixing of sounds seems to be an issue for alot of people and everyone preferes different things - how about we ask DTG to work on expanded sound options ingame. There you could increase or decrease the volumes of rail noise, the engine, horn and what else might be applicable. Engine is too loud? Decrease volume for that. Don't hear bogie sounds? Increase that. Wanna have a relaxing run? Reduce engine and track noise. I know DTG are currently missing personnel for UI, but maybe this is a solution that would work for everyone rather than one that works for a few people. Plus it makes the off-mixed reserved collection fixable by the user. Disclaimer; I know nothing about coding and programming so I have no clue if that is a huge task or if this is an actual alternative.
