Item 7.01.       Regulation FD Disclosure

On February 23, 2007, Norfolk Southern Corporation distributed its 2007 Investor Book, a copy of which is attached hereto as Exhibit 99.

Statements about future results made in the material furnished with this Form 8-K as exhibits constitute forward-looking statements that may be identified by the use of words like "believe," "expect," "anticipate" and "project."  Forward-looking statements reflect management's good faith evaluation of information currently available.  However, such statements are dependent on and, therefore, can be influenced by, a number of external variables - more particularly described and identified in our most recent annual report and quarterly report to the SEC on Forms 10-K and 10-Q - over which management has little or no control, including:  domestic and international economic conditions; interest rates; the business environment in industries that produce and consume rail freight; competition and consolidation within the transportation industry; the operations of carriers with which NS interchanges; acts of terrorism or war; fluctuation in prices of key materials, in particular diesel fuel; labor difficulties, including strikes and work stoppages; legislative and regulatory developments; changes in securities and capital markets; disruptions to NS' technology infrastructure, including computer systems; and natural events such as severe weather, floods, and hurricanes.  Forward-looking statements are not, and should not be relied upon as, a guaranty of future performance or results, nor will they necessarily prove to be accurate indications of the times at or by which any such performance or results will be achieved.  As a result, actual outcomes and results may differ materially from those expressed in forward-looking statements.  NS undertakes no obligation to update or revise forward-looking statements.
