In order to create punctual timetables, it is necessary to accurately calculate and plan out many values, such as running time between stations, headway between trains, train scheduling, rolling stock scheduling, driver and crew scheduling, operation scheduling in stations and depots and capacity of the line/infrastructure. Among these values, shortest running time between stations must be calculated first, as this is the basis of timetabling. This document describes parameters as the requirements for shortest running time calculation that enable railway infrastructure managers, railway operators and related organizations to calculate accurate running time at the stage of setting up a feasible and punctual daily and annual timetable. In addition, this document shows the appropriateness of calculation by verifying the response observed on the calculated shortest running time when the parameter values are changed. This document excludes running time calculation used for purposes other than timetabling.
