Reply to "All this expertise among forum members and yet still no command control "fix" for a conventional P.E. berk with the whistle steam effect?"

He's also asking how to do it in command mode, not conventional mode.  I actually have the means to cobble this up at this point, but I haven't gotten to building the "official" board that will support this.  I haven't actually looked at the PE locomotive in question to see exactly how the whistle smoke is done.  As I recall from discussions, it's actually a puffer with a little fan to tap off the whistle smoke.  My target is going to be for retrofits so I can add a smoke unit and get whistle smoke.
