The Genesis 4-8-8-4 Big Boy, like the 4-6-6-4 Challenger before it, is the culmination of design andtooling, integrating the latest innovations in electronic technology. The Big Boy model has been developed from the outset as the finest operating miniature representation of the prototype available. Giving life to all the details are authentic sounds that are channeled through a factory installed DCC and soundboard with speakers. The DCC decoder automatically senses what type of power supply is in use (conventional DC or NMRA compliant DCC) and adapts its functions. The modeler doesn’t have to do a thing.

The HO 4-8-8-4 Big Boy has functions and sounds available to DCC users including: Bell, Whistle, Water injector, Air release, Blower hiss, Fire box door, Lighting direction, Coupling, Brake squeal, Conductor’s voice, Sand release, Cylinder cock/flange squeal.

A handheld wireless controller is included for use with conventional DC power supplies. With it, modelers can control six sound functions as well as speed and direction.
