Inevitably for me, following the visible progress of roadbed
construction and track laying, the next necessary step—wiring—always seems to
be a “downer.” Nonetheless, wiring
is essential to making the magic of trains run. My prior post on wiring my railroad ( http://espeecascades.blogspot.com/2015/05/wiring-mountain-grade.html)
discussed why it seems to take longer for me to get track into operation. I am happy to report basic track wiring
has been accomplished on the mountain grade!
I distribute my DCC boosters around the layout to minimize
power and DCC signal losses. This
results in a “station panel” associated with each of the boosters. The panel for Wicopee and Cruzatte is
about as basic as such panels get for my railroad. The detection block wiring for a station is gathered into a
pair of terminal strips. These are
fed by a circuit breaker, which receives power from the DCC booster. Space is left on the station
panel for subsequent installation of block detection circuit boards and power
switch machine control boards. For
now, all the blocks get jumpered together.

One issue addressed in locating the DCC boosters around the
layout has been the installation of the NCE Control Bus between boosters. This is a four-conductor cable that uses
RJ-H connectors at each end. NCE
supplies a short cable with each booster, but longer cable runs are up to the
end-user. Unfortunately,
four-conductor flat cable and RJ-H connectors have vanished from regular
consumer supply houses. My
solution has been to run Cat5e cable between booster locations, splicing half
of the NCE-supplied cable onto each end.

Cruzatte. The green wire is a
ground needed among the boosters.
The gray wire laying on top of the booster is the Cat5e cabled that has
the NCE-supplied short cable spliced onto the end.
NCE specifies a “daisy chain” set of connections from one
booster to the next. My chain
begins with the command station under Springfield, passes through the boosters
for Eugene Depot and Oakridge and now connects to the large booster for the
Eugene Arrival/Departure Yard—the staging loop in the “back room.” From this large booster, the command
bus snakes back to a corner, up the wall and out on the upper level to the
booster for Crescent Lake (upper level staging). The command bus then has to back track to begin working it’s
way out to the booster for Cascade summit and McCredie Springs. Finally, the last leg extends around to
the booster for Wicopee and Cruzatte.
A look at my track plan will give you an idea of where these locations
are in my basement space.
With all of the cables run through the layout and end
connections made, it was time to see if I got it together right. My pair of Athearn GP35s that seem so
handy for these check out tasks, got called upon once again. They are seen in the photo below. Look closely, you will see the
headlight is on!
Locomotive check out of wiring to the track at Wicopee. The headlight is on and it runs!
I am getting very close to actually running over the full
mainline!
