# SUPPLEMENTARY INFORMATION:

In September 2007, the Board awarded a contract to Christensen Associates to conduct an independent study that provides a comprehensive analysis of a wide range of issues including competition, capacity, and the interplay between the two. After the study was released, the Board held a public meeting on November 6, 2008, with Christensen Associates to discuss it.

In August 2008, to supplement this study, the Board called for an analysis of long-term forecasts of freight rail demand, particularly the U.S. Department of Transportation's Freight Analysis Framework (FAF). The Board requested a review of FAF and augmentation of FAF to permit greater incentive-based responses by economic agents and to test the sensitivity of FAF to key inputs, such as fuel prices and rates.

                    The                     *Report*                     compares the FAF commodity flow forecasts to other macroeconomic and commodity-specific forecasts to develop alternative forecast scenarios of future freight rail volumes. The                     *Report*                     also analyzes the 2007 Cambridge Systematics study that used the FAF commodity flow forecasts to                           ( print page 16915)                        estimate the amount of infrastructure investment needed to meet the projected demand for rail service through 2035. The                     *Report*                     further discusses the role of public involvement in railroad infrastructure investment.                

                    The Board has made this supplemental report available to the public via its Web site,                     *http://www.stb.dot.gov*, and now seeks public comments and replies from all interested persons.                

This action will not significantly affect either the quality of the human environment or the conservation of energy resources.

Decided: April 8, 2009.

By the Board, Anne K. Quinlan, Acting Secretary.

Jeffrey Herzig,

Clearance Clerk.
