Reference section
A defined section of route used as a benchmark for time and speed measurements.
A reference section (German Referenzstrecke) is a precisely defined stretch of route used as a benchmark for time and speed measurements. Target times and average speeds are calibrated or checked against it, so that the scoring of a regularity test rests on a reliable basis. The length and course of the reference section are surveyed exactly in advance.
