On-Board DC Sound Module w/Tran (MRC500)

Sound modules from MRC bring easy-to-install sound to your DC locomotives without the fuss of adding a full-blown DCC system to your layout. The sound modules come equipped with the same eight-pin DCC plug that fits the socket inside many DCC decoder-ready HO locos. Each sound module includes an attached speaker and antenna wire. On your layout you control the speed and direction of your locomotive from your existing power pack, sounds such as squealing brakes, bell and whistle are controlled with the supplied wireless sound controller.
 
Includes sound module, speaker and wireless sound controller with six buttons.
