first of all I'm new to n scale and model railroading in general. i like railroading because I like to make dioramas. Anyway I'm using n scale e-z track and I want to know the radius of the curves used it says, there are 11.25 and 19 degree curves avaible.These are odd degrees to have. 19 doesn't even go into 90. Also i already have sdome 15 degree but you don't seem to sell those? The HO scale has a wider selection of degrees why not N? What are the true degrees for these curves and are there degrees out there?
While the prototype railroads generally refer to curvature in degrees, the number of degrees being the angle formed from the outside rail 100 feet from the measured location, modelers refer to the radius of a curve in inches. Both 11.25 and 19 refer to the radius of the curve in inches. Non-flex track usually comes in 15, 30, or 45 degree segments, or 24, 12 or 8 sections per full circle.
