N RTR 4-8-8-4 Big Boy w/DCC & Sound, UP #4019 OverviewThis stunning reproduction of the 4-8-8-4 Big Boy is the result of a focused determination to accomplish one thing: create 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. Functions and sounds available to DCC users include: 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. The N Scale 4-8-8-4 Big Boy includes a history book and instruction book for quick reference.
