Peco code 100 rail Y electrofrog turnout. These larger radius turnouts provide a smoother curve and better appearance for junctions without a significant increase in length. Y points are often used by the real railway to allow higher speeds on both diverging routes.
Length 220mm 8.7in, nominal radius 1828mm 72in, frog angle 12 degrees, each track diverging by 6 degrees.
Templates for Peco points are available from the Peco website.
