1 Web-Based Screening Tool for Shared-Use Rail Corridors This research was motivated by the Passenger Rail Investment and Improvement Act of 2008, which instructs the Federal Railroad Administration (FRA) to seek partnerships between freight and passenger railroads with a view to developing new passenger rail services that would support a growing economy and help relieve highway congestion.

3 SU Workflows SU is designed for preliminary screening of proposed projects that introduce new passenger service to existing freight or shared-use corridors. The tool is intended to be used very early in the planning process, where it offers a rigorous, systematic approach for establishing a framework or starting point from which more detailed discussions and analyses can follow.
