I'm always so fascinated by the sound of emergency brakes on any train, whether the sound or the sight, it would be nice to see some more sound effects besides just emergency brakes get added to the game.
On the American freights I find it disappointing without the signature air swoosh as the air gets dumped and the breaks apply. Another thing needed to be added is the GE air compressor sound when the brakes are released on the ac4400cw.
What compels someone to sign up to a forum, only to instantly reply to a 5 year old thread that they for some reason looked for, to someone who hasn't even been around for the past 3 years?
Adding other sound effects like rolling wheels, train whistles or station announcements will bring a deeper immersive experience. This not only increases the realism but also attracts players, especially those who love details in games. Your idea is great, hope the developers will consider this
