This stunning reproduction of the 4-6-6-4 Challenger 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.

The N Scale 4-6-6-4 Challenger includes a history book and instruction book for quick reference.
