Reply to "BlueRail engine using AC track power"

Sounds are limited to nothing with BlueRail unless you add a DCC board.  Then you're getting into real money for O-gauge currents.  Just the BlueRail board is $150, then you need a DCC decoder that will handle full sized O-gauge tasks.  Finally, you still have to add the DCC compatible sound board.

I think I can wait on this option until the costs get more in line.
