Ross switches for 2R....

Depends if you're using a "Ross-Ready" turnout or a regular. Ross wires the rails together on the Ross-Ready turnouts. All you have to do is cut the metal links that tie the running rails together and that should take care of the biggest short-circuit threat. The points aren't normally wired, so you should add a jumper wire from the appropriate stock rails to the points and closure rails to prevent stalling. The frogs are Delrin plastic, so there's no problem there. Look out for reverse loops and wyes.

If you're using the 11-degree turnouts, everything should run fine, but your wheels my bobble through the frogs. I don't have any experience with the #6 and large Ross turnouts, but you may have to put a movable point into the frog for the wheels to ride on as the gap might be too big. We added a moving frog point to a #8 curved turnout to support scale-wheeled equipment at the club layout.

Matt,

Will older Gargraves work the same way or should I avoid using them?

thx

I'm not a fan of Gargraves turnouts. The track is fine -- my scale-wheeled equipment runs on it just fine, except for kinks or badly laid track. Gargraves turnouts (IMO) aren't well constructed and have problems even with 3-rail equipment. Ross turnouts are much better. Make sure you avoid kinks (long wheelbase locomotives won't like them) and uneven spots in the track as the smaller flanges will ride up and derail (we use my long-wheelbase diesels to find bad spots now.)

If I was building a pure 2-rail layout, I'd use Atlas or Micro-Engineering 2-rail track. My home layout plans (at least for now) call for MTH ScaleTrax as it's well gauged and has a better rail profile. The down side is the turnout availability, but there are ways around that.

I would pack the vertical area in the frog.  That will keep the 2Rail wheelsets from dropping too low.  Then I would play with the clearance of the guard rails.  Use a standards gauge to check that.

 I also agree with using ATLAS track.  You could wire it for 2Rail or 3Rail.   Also remember you are switching from AC power to DC power.

I just thought about this....A buddy did this with Gargraves switches.  He also Filed a groove in the existing frog for the wheels to come through in the alternate or siding side?  Been a while since I have seen one.
