I may be in the minority but I really don't like having duplicates in sound, especially on these high dollar locos. I own almost every big Lionel steamer produced and part of what is so appealing to me besides the actual model itself and the awesome feature upgrades you all are doing is the unique sound sets. Being able to tell which locomotive it is from the sound of the whistle is pretty cool. I immediately thought Legacy 3751 when I heard it which was disappointing. I realize it may be more correct than the deeper tone, but I have to imagine there is more than one "correct" whistle that could be used that isn't exactly the same as a previous release.
You fellas are doing some great work over there regardless, I just want to know it's the AC9 when I hear it scream
