For years I was annoyed by the early Lionel steam locomotive sounds until they finally achieved four chuffs per driver revolution. (I was so annoyed when the 783 Hudson came out with its "sounds" of one chuff per revolution that I immediately sold it! With those large diameter driving wheels, it could be going 80mph and I got a chuff it seemed like every 10 seconds!)
But, I digress. The current LionChief steamers have only two chuffs per revolution. Why? Isn't the chuff rate now driven by the electronic package, not a physical cam?
Why are we back to two per revolution?
