The Athearn N Scale 4-6-6-4 Challenger, is the culmination of the art of design and tooling, integrating the latest innovations in electronic technology. The N Scale Challenger model has been developed from the outset as the finest three dimensional 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 DC) and adapts its functions. The modeler doesn’t have to do a thing. Era: 1940s - 1980s.
