The book "Railway Timetabling & Operations" offers a comprehensive analysis of modern methods in the field of timetable design and railway operations. In an era where the efficiency and quality of rail transport are becoming increasingly important, the work addresses central challenges such as rising traffic volumes and the optimal use of existing capacities. The updated and expanded edition of the book, based on the original publication from 2008, highlights advanced techniques for capacity estimation, analysis and modeling of train operating processes, as well as simulation and redesign of timetables. It is aimed at academics, students, and professionals in the railway industry, providing valuable insights for public authorities involved in railway services. The goal is to enhance the attractiveness and efficiency of the offered train services by better understanding the impacts of availability, reliability, and robustness of subsystems on train processes.
