SP&S Challenger - Athearn 4-6-6-4 Challenger w/Tsunami Sound & DCC

Road #911

Product Description

An incredible modelling of the 4-6-6-4 Challenger by Athearn is born of determination to create the finest operating miniature representation of the prototype available.  Athearn succeeded, giving life in all detail, even down to the authentic sounds from the factory installed 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. You don't have to do anything. The model includes a history book and instruction book for quick reference.
