FOR Circular Railroad Curves, This table contains the tangent distancesto a 1 degree curve for every two minutesof intersection angle to 90 degrees. The tangent distance to any other de-gree of curve may be determined by divid-ing the number correspondiDg to the inter-section angle by the degree of curve. 31 0 9 4681012141618202224262830323436384042444648505254565860 0° 28. 33 O .
