For Marx Monday we feature #424 Radio Train Control Tower. Just underneath the shanty you will notice a small lever. Picking the tower up in your hands, like a microphone, and press the lever saying "Start" or "Stop". The train is then supposed to obey your command. In point of fact, just by blowing or puffing into it momentarily breaks the electrical contact causing the engine to start or stop. It's pretty much the same thing as the Audio Engineer which was designed by Marx and featured in an earlier post. Enjoy!
