Book excerpt: "A railway line has finite capacity to provide transportation of goods and people at an acceptable level of service. The capacity of a particular route segment to satisfy railway traffic demand is largely a function of the track infrastructure layout and traffic control system. The amount of railway capacity consumed by a given demand for freight and passenger transportation is primarily a function of three factors: the number of trains required to transport the demanded freight and passenger volumes; the level-of-service requirements of each type of train; and complex interactions between different types of trains arising from the operating plan over a particular route segment. While much previous research has documented the relationship between infrastructure, traffic control and train volume, understanding the relationships between operating plans, train-type interactions and train-type-specific levels of service is still a knowledge gap. This research explores these latter factors in more detail and develops new capacity evaluation and infrastructure planning techniques to account for their effects. The first phase of this research will use RTC simulation and analytical techniques to develop a capacity evaluation process for shared corridors with multiple types of trains that each have their own level-of-service requirements. The developed process will be applied to a representative corridor to draw general conclusions about the impact of passenger trains on shared corridors with different mixtures of freight train types. The second phase of this research will use analytical techniques and RTC simulation to develop a new parametric model for the distribution of train delays on a single-track shared corridor. The third phase will develop an analytical screening tool for identifying appropriate infrastructure and operating solutions to increase capacity of shared corridors. The final phase will develop an optimization model for selecting siding locations on single-track shared corridors with structured timetable operations."--
