I'm new to DCC, and have just added DH123 decoders to my P1K Milwaukee Road A-B-A Erie Built set. The loco numbers are 21A - 21C - 21B, which I've programmed as addresses 20,
21, and 22 (since a C-Liner is already address 23). I'm already seeing it is a pain to MU these units, and that with simple MUing, the headlight on
21B does not come on when it's the lead unit (it thinks it's going backward).
I notice in the Digitrax documentation that it would be OK to reprogram all three locos to address 21, being sure to set CV-29 for the 21B unit for normal operation in reverse. I plan to run them as a 3 unit set most of the time, and sometimes with one unit removed as the Milwaukee Road ran them in the 1950's. I don't plan to operate with Chance cards ("Main bearing failure on 21C; set out unit at next siding"), so I see little benefit in having the capability to un-consist the set and run a unit separately. How do you more experienced DCC operators modeling the early diesel era when multiple units were viewed as a single locomotive set up your multi-unit locos, and why? Geezer
