ISO/DIS 24675-2 is a draft international standard focusing on railway applications, specifically for running time calculation and timetabling. It details how to use distance-speed diagrams and speed curves to create and verify running time calculations, ensuring accuracy in railway schedules. The standard defines a practical procedure for creating these diagrams and curves, using parameters specified in ISO 24675-1, and includes a method for obtaining the shortest running time through numerical integration.
