Abstract

This document specifies a practical procedure to create and verify distance-speed diagrams and speed curves using the parameters specified in ISO 24675-1, from which the shortest running time for railway timetabling is obtained by numerically integrating the speed curves.

This document excludes running time calculation used for purposes other than timetabling.
