Inner rail edge

from Wikipedia, the free encyclopedia
sketch

In the case of railroads, the inner edges of the rails are the inward-facing surfaces of the two rails of a track.

These two areas are required to determine the center of the track and the gauge , which in turn are of great importance for railway construction. The calculated inner edge differs from the geometric one and can be determined differently depending on the rail cross-section. The flanks of today's UIC rails are inclined 1:20 and open at the upper end of this incline in a radius R = 13. This transition point from straight line to radius is the theoretical point of contact between wheel and rail and serves as the definition point for the inner edge of the rail.
