24
Up the Creek Column - 10
the promise I made to my operators that we’d be running op ses-
sions before the end of January.
A lot of turnouts remain to be built and installed in South Jackson
for the yard’s body tracks, plus I need to get the South Jackson
turntable installed.
24: One more problem. The
first train made it all the way
through South Jackson and
was entering Mill Bend when
“beep beep beep”, we had
another short.
The South Jackson and Mill
Bend blocks are powered by
two different boosters. When
the loco bridged the bound-
ary a short occurred. A quick
check with a digital multi-meter
revealed the two blocks had
opposite polarity rail power.
It appears that when a Digitrax
DCS-100 and DB-150 are run
off a common LocoNet, the
Rail A and B outpus of the
DB150 are reversed from the
Rail A and B outputs of the
DCS100. When the loco con-
nected them, a short circuit
occurred.
I swapped the Rail A and B
wires on the DB150 and all
was well again.
All I can say is “I’mworking
on it” and things are looking
promising.
Time will tell.
