Just curios, does anyone make a sound board (or something I could use from another engine) that could be used in a prewar standard gauge of o gauge engine (electric type engine type not steam) running conventional power.
Would like the sound board to have a simple whistle/bell and a engine whine that is changes in volume/whine that is controlled by the amount of power applied to the engine.
Know that real estate my be a problem on O-gauge and that a battery (?) may be used when there is no track voltage.
