Yippee! we have sound again for the CSX freight cars. But another problem was created. On my end I did a short scenario with the Coal Hoppers and after I've disconnected them from the locomotive a sound started to play from the hoppers, it was the sound that gives the impression that they are moving, or breaking to slow down, rattling etc as if they are moving but in reality they are at a stand still. So yeah.....Haven't tested the other types of freight cars yet
