The other day I got to looking around the Train-Sim library and couldn't help, but notice that there aren't too many 1-chime steam locomotives whistles that sound that good enough.
One's that I'm thinking of include those from the N&W or C&O. Such examples as that, don't really have any good enough versions of these whistles available in MSTS, almost as if they're being completely over looked... Why is that?
