Digitrax DN163A1 - N Scale 1 Amp Mobile Decoder for Atlas Locomotives

N Scale 1 Amp Mobile Decoder for Atlas Locomotives Features: - Board replacement decoder for Atlas N-Scale SD60, SD60M, SD50 and others - Golden-White Surface Mount LEDs for added realism - Decoder Lock equipped Note: In January 2012, DN163A1 was changed from larger through hole LEDs for lighting to smaller surface mount LEDs. Both versions work the same way. This was a manufacturing change to make the process more efficient. Do not settle for a decoder without the latest features in your locomotive!
