An
Automatic Reverse Loop Turnout Controller can be used in conjunction
with an ARSC to create a fully automated reverse
loop.
When doing a normal ARSC installation,
you will have north and south portals in the loop, as shown at right.
With the ARLTC wired without an optional portal, the train will enter
one way one time, and the other way the next time - continually alternating
back and forth.
If you want to control which way the
train goes in, you can install a trigger button to the north portal,
and another trigger button to the south portal, covered later.
If you want the train to enter the
same way each time, you can install an optional portal as illustrated
at right. This portal absolutely must be far enough from the turnout
to contain any train that will go through the reverse loop - because
the tail end of the train has to clear the turnout before the loco crosses
that portal when coming out of the loop.
Loy's Toys no longer manufactures ARLTCs,
but it's easy to make your own. |
