HSR Cost Estimating Techniques in Pennsylvania

Using a personal‐computer‐based spreadsheet program, costs are estimated by technology and by alignment segment to provide estimates of total costs and the basis for comparison of alternatives for high‐speed rail implementation. A preliminary analysis is first performed to focus major efforts on significant cost elements. In addition, functional and spatial requirements are determined for stations and maintenance facilities to provide a rational basis for the estimates. Manufacturers are consulted to provide physical and operational requirements for the range of technologies under consideration. Capital cost comparisons are made between several HSR studies and available implementation data for rail and Maglev systems to provide a better understanding of the range of values observed and to assess those factors that may contribute to cost estimate differences. A recommendation is made to adopt uniform standards for the estimating of capital costs for HSR systems to allow better understanding and comparison by the financial community, public officials, and private interests.
