DCC Programming

[Georgia Flash]

To: Randy;  David B.;  Crandell;  and others here.... Many "Thanks" for your responses. I feel real stupid

EPIPHANY!!!  After internet and "Googling" in search of answers, I came across information that suggests that  YOU CANNOT OPERATE BOTH DC and DCC-equipped locos on the same track, period. It seems that it's safe operation with one-or-the other; but not both. It seems to make sense: Using DCC sends constant current through the rails, a sure-fire way to eventually overheat and possibly burn up an analog/DC motor.

After a tech-support person at Digitrax guided me through "programming" a DCC-equipped loco (which works...,  finally), I tried operating an analog/DC loco with the left throttle knob and the decoder-equipped loco with the right throttle knob and,  Tada!  The decoder-equipped loco operates fine; the DC loco just sits and "sings" (and I removed it from track because the 'singing' is not a good sign). Am hoping my logic and understanding make sense here; that I'm on the right "Track"... Thanks, again.

G'Man,

You should really include this respond in your other thread rather than creating new threads.  Since it's inevitable that the two threads won't stay together on the same forum page, others piping in for the first time (who haven't seen the original thread) may end up asking some of the same questions.  It just makes it easier to follow.

Two or three systems will run a DC loco. Sitting still is hard on the motor. I have done temperature checks with a infra red temp scanner. The brushes can get quite hot right were they contact the armature. I could pick out that hot spot even with a can motor.

I use to run a couple DC locos with an old MRC2000 DCC controller.

I belong to about twenty MRR/DCC forums and the biggest issue I see is assumptions based on DC operated locos which is surprising as the Internet is loaded with all kinds of DCC info.
