Notes:
At some point in the production, S-Helper Service switched away from the Soundtraxx decoder for these engines, and started using the QSI Revolution sound decoders. This was due to the current-draw that maxxed out what the Tsunami could handle (this was the original Tsunami; the Tsunami 2 may be able to handle it).
