DC/analog sound module for USA Train EMD NW-2
Thanks to an eagle-eyed relative with a generous and optimistic nature, I am the lucky recipient of a small but complete working G-gauge setup culled from a multiple-box yard sale haul simply marked "trains".
I'm testing it all before the grand unveiling to my son, which will be a grand day.
The setup consists of:
Aristo-Craft oval track + 4 straight pieces, which builds out to about 10' on the long axis with the extra pieces installed
CMI "The Sounder" 40M transformer/controller
USA Trains EMD NW-2 diesel switch locomotive with "New York Central" markings
and a couple of cars
My question is: What are the options for installing an on-train DC-powered sound device? I tracked down the manual for the engine, but apart from mentioning that there are power connectors on the engine to power lights and sound, there is no information.
Any recommendations or pointers to articles that explain how to determine what the options are here would be greatly appreciated, as I'm not well versed in this realm, and a lot of what I'm finding seems DCC-based.
