for rail passenger ridership and cargo traffic, benchmark assessments were undertaken to provide preliminary estimates. Engineering unit costs were derived from recent studies across the US, including the Midwest,Mid-Atlantic,and Florida. These unit costs were then applied to route profiles for various Highway 52 corridor alignments. The output of the interactive analysis will be an operating and cost/benefits ratio for each route/technology option that optimizes the financial and economic benefits of the potential infrastucture,technology and traffic levels
