As worldwide demand for passenger and freight transport increases across all modes, main line railways in Europe are experiencing ever more intensive use of their services, particularly in urban areas. At the same time, much of the existing mainline railway network has been already susceptible to delays and disturbances. One solution to this problem is to build more railway capacity; however, constructing new railways is expensive, takes time and faces a number of environmental constraints. Therefore, we investigate new ways of managing existing capacity that will allow more services to operate more reliably and increase passenger satisfaction. This project is supported by European FP7 project Optimal Networks for Train Integration Management across Europe (ON-TIME).
