Network-based systems are at the core of our everyday life. Whether it is electronic
networking, electricity grids or transportation, users expect the networks to function properly …

Many infrastructure managers have the goal to increase the capacity of their railway
infrastructure due to an increasing demand. While methods for performance calculations of …

Railway capacity planning aims to determine the amount of traffic that can be operated on a
given infrastructure. The timetable compression method described in UIC Code 406 has …

Urban rail transit operations are susceptible to unexpected disturbances or disruptions, with
rolling stock faults being a particularly common cause. Therefore, this paper focuses on the …

Due to high demand and capacity consumption, railway timetables are often sensitive to
disturbances. To maintain punctual operations, it is important that timetables are robust, and …

Railway operations are organized according to a complex interplay of resources and
according to a rigid time separation of train runs over infrastructure elements. The system …

In Sweden and other countries it is not an uncommon practice that freight trains depart more
or less on-demand instead of strictly following a pre-planned timetable. However, the …

Railway systems form an important means of transport across the world. However,
congestions or disruptions may significantly decrease these systems' efficiencies, making …

The transport capacity of an urban railway line can be increased in many different ways. For
planners and infrastructure managers it is vital to have all the tools available that allow …

Robustness is a crucial concept in railway timetabling. It is often related to the ability of a
timetable to absorb small delays. We propose a MILP model to improve the robustness of an …
