I know that the distance from the bottom of the ties to the top of the rails for GG is 7/16", but do not know the corresponding # for Atlas. Help me, please.

O Scale Track FAQs
Why does the 3-rail atlas o 21st Century track system use the size rail that it does?
How was the overall height of the ties and rails determined?
This can be explained simply with one word - “compatibility”. It was essential that our track system be readily incorporated into existing layouts
using other lines of product. The combined rail and tie height was carefully engineered so that it would match the overall height of Lionel and
K-Line 027 tubular, Lionel Super-O, Curtis, Ross and GarGraves. When Atlas O track is placed on traditional 1/4” thick cork roadbed, the height
will now match O tubular. We also offer a variety of transition joiners to make connections to other track brands quickly and easily.
Atlas track aligns perfectly height-wise with Gargraves. You don't have to use the adapter pins. I actually recommend against them because they're a little flimsy and leave gaps. You just shave the webbing from the bottom of the Gargraves track and use regular Atlas joiners and everything lines up. We use Atlas track for all new track and realignments and use the Atlas joiners. It has worked great.

Thx, guys.....Just what I needed to know!
Wish I had known that a couple of years ago when helping a friend of mine with his layout in Lantana FL. I could not get the two types of track to line-up, Lionel O tubular and Atlas O, could have used a section of Gargraves between the two other pieces of track and used Atlas track clips to Gargraves, very easy.
I have tried using the Atlas adapter pins and must say they are very flimsy and difficukt to stay aligned, and that's with O tubular.
