ModelRailroadForums.com is a free Model Railroad Discussion Forum and photo gallery. We cover all scales and sizes of model railroads. Online since 2002, it's one of the oldest and largest model railroad forums on the web. Whether you're a master model railroader or just getting started, you'll find something of interest here.
Look on the fast tracks site under the forum ,look in the HO Scale section for a long thread on wiring the double crossover, the fastest and easiest way is to use the Hex Frog Juicer, you can also use tortoise machines and a reverse unit to control the turnout. As far as the Shinohara diagram i don't think that will work as Fast Tracks do not use jumpers between the rails and location of gaps that make the bounderies of the isolated areas. Clint
I just tried mine, not wired yet either and my engines are going thru fine also, just a little hesitation going thru at low speed with my Berkshire and 2-10-2 and some others. Now I'm puzzled. So far i have only run straight up in till now, thought i would have to help the engine thru the turnout until i wired it.
Two possible reasons: first, those turnouts are engineered very well, and if assembled properly, they power all routes except for the frogs. The frogs would only be a problem for older engines and shorter wheel base ones. I can get my SW8 with DDC/sound through my handlaid #10 curved turnout without a hitch. The frog on that sucker is long!
Secondly, keep-alive circuitry in better decoders gives the engine an edge.
One thing that can trip you up over time is if the crossover isn't supported well below it, particularly at the joints. Joiners that flex will eventually fail mechanically and you'll get intermittent performance problems. If you are careful, joiners that are kept clean and well supported should last for years, but there is always soldering...or jumper around the joins. You can quickly heat one end of any jumper wires, pull them away from the rails, and slide back the joiner to remove the crossover if you ever need to.
If your frogs are isolated as they should be, and you have built these according to Tim Warris' specs, I would not be surprised that they'll get fed exactly the same way in DCC as they do in DC, and that is via the joiners and powered rails beyond them.
Basically, if they work in DC, they'll work in DCC.
