N Con-Cor 4-8-4 Steam PRR w/DCC function Decoder
All Digitrax decoders come with analog mode conversion, when no dcc signal is detected they will operate as DC locomotives.
There are a few caveats however: The DCC decoder will not wake up until ~6v are present on the track, this means whatever speed the loco moves at 6v is the slowest it can go, so low end operation is affected. Some decoder equipped locos may not operate smoothly on conventional “pulse power.” DCC equipped locos should be driven from a quality smooth DC power supply when on a conventional layout. Some DC throttles/power supplies with proprietary control systems, such as “tracking control,” exhibit pulse power characteristics and may give unpredictable operation.
