Double reverse

I have been looking at something similar for a corner of my layout.  The only possible problem area for you are the back-to-back switches in the center.  I don't know about Gargraves switches, but the rollers on some of your engines could possible find dead spots with this arrangement and the engine will stall.  I don't think this would be an issue with O42 switches, but it was with the back-to-back RCS O72 switches on my old layout.

Anything that can work on O31 curves should not have a problem with the S curve the O42 switches make.

I made a circle of O72 track and replaced the track where needed with O72 switches.  You could do something similar with all O42 track and switches.

Technically, the two switches in the center could be replaced by a crossing, without changing the reversing effect. That might help simplify your wiring too. Then you could reuse the switches elsewhere.

Is this going on a table, or just the floor?

Not true, A crossing would not work like the switches do. If you wanted to go in a circle, you couldn't do it with a crossing.

Of course it wouldn't, but the small circle has little play value, as this is only a piece of a larger layout. Now a double slip would provide the same function, but it complicates things too.

If he's willing to sacrifice the small circle, he can simplify the wiring greatly, thus relieving his concern as posted. I think the point of this design is the reversing capability in both directions, not the incidental small circle it creates.

That's just my take on his post, thinking outside the circle as it were.

JHF,

  Ron is right to set this particular design engineering up so it can run bigger engines you need to look at 072 curves and switches, if you have the room to do it!

Starting to set up inside reverse is only for 031 engines, outside loop is 072 for my big stuff. There is a 5" section between the 2 eyes for better current flow. The 072 will join my larger loop on the main that uses 072.

Running electrical test using GEEPS to test switches.

This will be powered by a Z1000 powered for   Legacy  DCS, Lionchief & conventional a and keeping power isolated from main line Z4000.

The last version is much better -  I suppose that you are going with what ya got in track inventory -

I came up with this for half of a double wye before I saw the last post - GG track & switches with a Ross O42 wye
