Bachmann DC/DCC Sound Value PRR GG-1 Engine

[Mham0359]

I am running this Bachmann GG-1 #4935 Engine strictly on DC and wish to turn OFF the Sound coming from the engine. Is this possible without taking the engine apart to get to the internal workings of the engine? I am using an old DC ONLY Railpower 1370 Controller/Transformer.

Sure...if You can disconnect one speaker wire...or have anyone (or a local club) with a programming track set F8 to ON
