A system for generating realistic train sounds which are synchronized with the motion of a model train. A sensor is placed aboard the model train to sense the position of desired components, such as the driving pistons of a model steam engine. Preferably, sound data is gathered and transmitted as a radio frequency signal from the model train. The radio frequency signal is received by an external receiver/amplifier. This component amplifies the synchronized sounds and plays them through a subwoofer which is capable of producing deep and resonant sound.
