Expand your train layout with narrow radius curved track! Each track piece is fully compatible with standard L-Gauge train track. The R value refers to the radius of the circle the track creates. Standard curves are R40: a 40 stud radius circle. Thus R56, 72, 88, etc create a circle 16 studs larger than the step below, allowing you to run parallel curved track with 16 studs center to center.
R32 is only a half step in size down from R40. Note that 15 pieces make a circle, which is an odd number. It is not possible to make a half circle.
