Wiring and Tortoise Installation
by cshutchinson on Jun.03, 2009, under DCC / Wiring
This week I have been working on installing the tortoise switch machines and installing the drops from the track to the DCC bus lines. Each rail gets its own feeder to the DCC bus lines. The isolated frog of each switch also gets one drop so the tortoise can control the polarity to the turnout frog. This will allow the motive power to crawl slowly through the turnouts. All is going well so far.
Tomorrow I will start mounting the two Digitrax DS64 units that will be required to add DCC control to these six turnouts. At that point I can also add my 12v DC power runs to each DS64 and wire up the Tortoise switch machines. I use DIN rail mounted terminal blocks with jumper bus bars to tie the rail drops into the bus lines. Here are couple of pictures of the progress so far.
In the following picture you can see the wiring drops from each turnout’s isolated frog.
