My layout is a two track, twice-around loop folded over itself. I placed a double crossover between Main 1 and Main 2 to provide access to a yard lead. When the double crossover is reversed then trains cross from Main 1 to Main 2, and upon coming around again from Main 2 to Main 1. The two track main becomes one track.

The layout also incorporates two reversing loops that cross each other. If both loops are reversed then trains do not change directions but traverse both loops. 

I just finished attaching all my feeder wires to the 4 individual buss wires coming into my helix space. And I cleaned all the track with mineral spirits and extremely fine emery type sandpaper.

My thoughts are this is a good time to apply some No-Ox to the tracks in the helix, and leave it set for a week or so before wiping if off (BTW I do know the caution about applying it lightly). My question is if I should eventually decide to put additional feeder wires on some of the track sections, how difficult is it to solder track that's been treated with No-Ox ??

I've been finishing up my buss and feeder wiring of the lower deck of my layout (and by extension the external helix structure).
 

Good evening,

We are heading down from Ohio to Raleigh, NC to set up with the S&SS of NC modular group this weekend.

They have a layout planned that will encompass slightly more than 25,000 sq. ft. of space in the Jim Graham Building, North Carolina State Fairgrounds, Raleigh, NC. 4285 Trinity Road, Raleigh, NC.  This layout is part of the Neuse River Model RR club's show.

Please stop by and say "Hi" if you're able to come to the show!
