Detailed explanation of R40 radius

R40 is the radius measured from the center of a circle to the centerline between the rails using the LEGO® stud as the unit. A LEGO® stud is 8mm.

The space needed to have the full R40 circle can be calculated as follows: (40 + 4) * 2 * 8mm = 704mm = 0.7m.

This measures the diameter (2 * radius) of the outer shape of the track - that's why we added 4 studs in the formula.

In general, the formula for calculating the outer diameter of a circle track is:

(R + 4) * 2 * 8mm
