A Library for Train Timetabling Problems

We introduce (TTPlib), a data library for train timetabling prob- lems that can be accessed at http://ttplib.zib.de. In version 1.0, the library contains data related to more than 100 scenarios. Most in- stances result from the combination of macroscopic railway networks and several train request sets for the German long distance area con- taining Hanover, Kassel and Fulda, short denoted by Ha-Ka-Fu. In this paper, we introduce the data concepts of TTPlib, describe the scenarios included in the library and provide a free visualization tool TraVis. This work was funded by the Federal Ministry of Economics and Technology (BMWi), project Railway Slot Allocation (in german Trassenborse), grant 19M7015B.
