      My comment was not controllable in real time. This is true whether you use a function controller or not. If a function controller is used, you can trigger the bell, and get the same 8 rings every time, or trigger the whistle, and get the exact same crossing whistle every time, just like triggered from a magnet . Real time means ring the bell while backing up, sound a few toots at start up etc.

      "The sierra will work for large scale, it will not be controllable in real
      time by airwire, the Sierra is not DCC and is very old design. "

      You can use a small function decoder to control the sounds on the Sierra board. Connect the function decoder board to the DCC output of the G3, then use the outputs of the function decoder to trigger the four sounds on the Sierra (Bell, whistle, hiss, and coupler clank.) I'll have to ask my dad to diagram exactly how he has his wired, but it works well. Digitrax and TCS make cheap (c. $17) 4-function boards that are about the size of a dime.

      Granted, I have to agree that the Sierras are old technology and pale in comparison to what you can do with a Phoenix connected directly via the DCC output (especially if you have the PC programming interface to tune the board to your locomotive.) But if you've already got the Sierra and all you're after is basic sound, you're good.
