Effective Radius at the Tangent Point and Its Uses

The aim of the paper is to estimate the effective (functional) radius at the tangent point, and to demonstrate its use to compute the track construction tolerances and speed on a non-spiraled curve. The existence of lateral acceleration at transition point between tangent and curved track indicates that the radius at the tangent point must have some functional finite value. The effective radius is estimated by using the principle adopted in BS EN 13803-2:2006 to determine the effective radius at the switch point of a turnout placed on a tangent track. A method is suggested to estimate the construction tolerance of a new track and speed on a non-spiraled curve from the concept of the effective radius. The concept of effective radius seems to have useful applications.
