OK, here are the new whistles. I've also found out how to make the engine be heard from farther away. All you have to is go into the proxyxml file, and change the activation distance. The measurement for this is in meters so I changed it from 400 meters to 1609 meters, which is equal to 1 mile.
Nathan 6 Chime 2014 (This one has a little bit of chuffing in the background, but it is not as noticeable in-game.)

C&O Single Note Hooter 2 (This one also has a little bit of chuffing in the background and it is noticeable when the train isn't moving, but it is the best I could do.)

I'll keep both versions of these whistles in the pack.
