Just a quick question for ya.
What is the turning radius of the atlas code 55 #7 n scale turnout? Thanks for the help.

‘Numbered’ turnouts have no real curve radius, as they are an angle divirging from the tangent track. The NMRA standard(RP12.7) list the ‘replacement’ radius as about 62" radius for a #7 turnout. The actual raduis from the tip of the points to the frog varies as the distance may be different with each manufacturer.

Atlas says a code 55 #7 uses a 71 inch to bring it tangent. They sell this piece as a sectional unit.

The #5 uses a 30 inch, also available.

Thanks a lot for the help. I’m trying to maintain a 15" minimum radius on my layout and it looks like these turnouts will work great.
