Reversing Loops- Alternative Hookup
To turnouts
wired in parallel
switching
opposite.
Hookup:
Attach #3 to the isolated center track section, upper rail as shown. (if incorrect there will be a short circuit)
Attach #4 to the isolated center track section, lower rail as shown. (if incorrect there will be a short circuit)
Attach #5 and #6 to a 12VDC power source. Polarity is not important. See power page for more info
Attach #15 and #16 to the turnouts wired in parallel. Turnouts should switch opposite so the train
follows the arrows as shown.
Jumper #18 to #19 and attach a wire to the negative power source
Jumper #17 to #20 and attach a wire to the positive power source.
Attach transformer TRACK outputs of transformer to track as shown. Each loop is isolated and hard wired for a certain
direction. Make sure the polarity and directions of the trains are as shown. For large scale trains in nautical terms,
“
PORT IS POSITIVE
”.
For LGB style trains the left rail is always POSITIVE while the right rail is NEGATIVE.
Notice that this is reversed for
trains following NMRA standards such as HO, N, etc. and the trains will go the opposite direction as the arrows indicate.
If the trains do not follow the directions as shown by the arrows then switch the transformer direction.

LGB 10151
Reverse Loop Set
Two places.
Using the LGB 10151 Reverse Loop set reduces the wiring complexity, but adds to the
overall cost by over $100. (This part is not available at RR-Concepts.com)
Trains will also go at a slightly slower speed due to the 1.4V voltage drop in the loops.
