15" radius curves

[sour rails]

     Does anyone know what angle of curvature is for the 15" radius curves.  For example, the 18" r curves are equal to 30 degrees each piece, making three to be used for 90 degree curves.  Are the 15" r curved pieces the same as 18" r, or do they have some other degree of curvature?
Thank you,

I'm pretty sure that 15" radius is also 30 degrees

The most easily available pieces of 15 inch radius track are made by another company (ATLAS) and have the same degrees of curvature per section of track as their  18 inch radius track which is 30 degrees.

15" radius track, Item No. 44505 (4/card)..

4 pieces of track make up one third (120 dgrees) of a 15 inch radius circle.

Trust that helps.
