I'm getting back into Lionel trains after a long hiatus. I run all my stuff from postwar transformers (ZW, V..etc.). I want to add a sawmill, and I like the sounds produced by the newer ones that operate with command control. Is there a way to operate one of these newer sawmills that have the sound feature using just an on/off switch like the postwar sawmills? I'm okay with electronics/wiring/soldering and would be willing to cut into the cables of the sawmill if necessary. TIA, Rick
