to heat build-up and is much happier with an external way to
dissipate some heat, as I’ve discussed several times.
12. It’s OK to run DC and DCC at the
same time
Another topic suggested by Mark Gurries.
I’m sure the source of this myth is folks who are trying to
ease the transition to DCC. Over the years, I’ve seen many
ideas of how to mix the two technologies on a single layout at
the same time.
If you want to go this way, wire your layout with DCC in mind
(large gauge bus wires and frequent feeders). If you design in
some block switches, make sure they are heavy-duty automo-
tive type (rated 10 amps or more), not micro-miniature toggles.
Don’t use any DCC-only accessories, like reverse loop controllers.
Then, use a connector between your DCC system and the layout.
I currently use a two-pin con-
nector from Molex that is rug-
ged, reliable and inexpensive;
previously, I used Cinch-Jones
connectors. That way, you can
unplug your DCC system and
plug in a DC power pack and
run the layout on DC, if you
want to do so.
The danger of simultaneous
running is the possibility of
interconnection between the
two technologies, even when
they are on separate tracks.
