Thanks for the info Bill, but unfortunately I tried all of this, and still no luck. I'm waiting for the local Hobby Town USA to open, to see if they will exchange it.

I just received the Large scale Silverado train set and can not get the sound to work, I have a new 9V battery installed correctly, the adjustable knob turned up under the car, and the wires correctly plugged into the back of the engine, with the master switch on.

Has anyone else encountered this problem?
