peco’s diagram is both precise and vague at the same time. Isolate the entire slip and power it as its own block using the two wires provided at the X.
I have three Cabs. DC. I’m using Insulfrog power routing turnouts each in a flanking siding to connect each end one of the slip crossings. At the moment one of those is a Unifrog but it can become an Insulfrog with two snips of the closure rail jumper wires. The other crossing track is a siding between those other two.
All theee sidings are powered from the turnout end and are dead end except for these escape turnouts.
Do I have to isolate the slip as Peco says?
If I do not, do I have to use power routing turnouts or can I leave the Unifrog turnout as is, all powered.
Not a frog question, just s stock rail power question,
Well, all four sidings are powered all the time when any of the yard blocks are powered on.
I now have wired in an Atlas connector and made the yard one block. Each entry turnout is double isolated at the entry end (although we use common rail so only the black wire is in fact isolated.) The connector switches are now connected to each siding separately but they have no effect. I’ll install black rail isolators to restore separate power control to each siding but one (the Atlas connector allows four separate tracks to be powered but only three can be switched on and off separately, the fourth is controlled only by the block selector.
I’m not sure how the power to each siding is bypassing the power routing through the Insulfrog turnouts. The double slip is a Unifrog. I even drew the blue and red rails diagram and this situation still isn’t showing up.
I isolated the black rails on two sidings which allows one siding to be powered on and off.
One pair of each escape crossover is fed power from the frog end only which complicates things somewhat because the turnouts are power routing.
The Unifrog double slip is not power routing but the two turnouts connecting the crossing track are Insulfrog do should power route but do not.
Interesting problem.
