  • Abstract:
    A growing demand for passenger and freight transportation, combined with limited capital to expand the United States (U.S.) rail infrastructure, are creating pressure for a more efficient use of the current line capacity. This is further exacerbated by the fact that most passenger rail services operate on corridors that are shared with freight traffic. Tools and methodologies for capacity analysis are one approach to investigate the situation. As the U.S. continues to develop higher speed passenger services with similar characteristics to those in European shared-use lines, understanding how such analysis are done in both continents grows in relevance. A detailed investigation was done to understand how each continent approaches capacity analysis, and whether any benefits could be gained from crosspollination. It was found that there was no major divergence between approaches or criteria used for capacity. However, there are differences in the tools used in these two regions, as the tool designs follow the main operational philosophy of each region (timetable based in Europe vs. non-timetable based in the U.S.). Timetable management is one of the operational methodologies commonly applied in the highly structured European rail system to improve the capacity utilization while maintaining acceptable level of service (LOS) parameters. The potential benefits of using similar methodologies to benefit the less structured U.S. system were studied in this research. A Hybrid Simulation approach was developed as part of the research to investigate the use of timetable management features and to analyze the tradeoff between LOS parameters and capacity utilization in the U.S. In the method, the output from Rail Traffic Controller (RTC), a simulation tool commonly used in the U.S., was used as an input for timetable compression by RailSys (a simulation tool developed in Europe).
