Posted by Jeff H. on Sun Oct 2 00:23:29 2005, in response to Re: NYC Minimum Curve Radius, posted by JayZeeBMT on Sat Oct 1 07:40:57 2005. Curves can be measured either in terms of radius or "degree".The latter method refers to how many degrees are turned when traversing 100 feet of the curve. For up to moderate curves of about 20 degrees, the formula R=5730/D, where R is the radius and D is the degree of curvature, is reasonably accurate. For sharper curves commonly encountered in transit or street railway work, specifying the radius is more accurate. |
