Abstract: Computer-based models and analytical techniques are powerful components of infrastructure management systems. However, the availability of data sets significantly affects the usefulness of such systems. The primary objective of this paper is to discuss the development of Geographic Information System (GIS) based data bases that would support management systems for rail infrastructure. It also discusses applications of such systems for risk and routing analyses including hazardous materials shipments. Specifically, the paper addresses the development of a GIS-based system for rail infrastructure with respect to several key elements and characteristics of a typical mainline railroad track. Examples of these elements include geographic alignment, longitudinal gradient and elevation, sidings, bridges and culverts, and at-grade rail/highway crossings.
