dcc & 3way shinohara turnoutgreenspun.com : LUSENET : Wiring for DCC : One Thread
How can does one wire i 3 way turn out for dcc? Is any change required/possible for one which is already installed.

Working up the three-way Shinohara track list is on my long list of to-do's.
If you the three-way in question is installed, don't wait for me to get around to working up a drawing for it. Converting one in place won't be any fun. Use 1156 tail light bulbs as outlined in my web page.
If you still want to convert it, you will be able to do so when I do make the drawing. Putting the tail light bulbs in now won't be a waste. They are always a good idea.

Peter, I have 2 Shinohara 3 ways on my small switching layout. I wired them as follows, and have no problems. Treat them as if they are two seperate turnouts, feeding power to the right and left frogs in the same way you would if they were in fact seperate turnouts, and cutting gaps after the frogs where you normally would. Ignore the first frog after the points. For want of a better term, and to display my ignorance, I call this the "center" frog. Works like a charm. I shouldn't say I have no problems--the turnout will short if I throw BOTH sets of points to the diverging routes at the same time, but why on earth would anyone ever want to have both set to diverge at the same time? BTW, Shinoharas have a nice hole in the spacer(?) bar near the point pivot--I drop a wire down this hole and tie it into the frog wire--this takes the pivot hinge out of the electrical loop. I haven't done any "dcc friendly" conversions to my turnouts-- cutting gaps at the fouling point, and trying to pay attention and not run up against an opposed turnout works for me.
