                          SAFETY INCENTIVE PLAN

                  FOR NON-OPERATING AGREEMENT EMPLOYEES

A.    INTRODUCTION - The Norfolk Southern Safety Incentive Plan for
      Non-Operating Agreement Employees ("SIP") is designed to provide
      an additional incentive to work safely through Safety Incentive
      Awards ("Awards") to eligible agreement employees who work
      without injury during the contest year.

B.    ELIGIBILITY AND COVERED EMPLOYMENT - An "eligible employee is an
      employee of Norfolk Southern Corporation or one of its rail
      subsidiaries or affiliates (the "Company") who works in a
      department or unit in Appendix A during a calendar year a
      sufficient number of hours in "covered employment" equal to that
      required to earn vacation.  "Covered employment" is employment
      in a position covered by a collective bargaining agreement.
      Partially excepted positions classified as 3A or 3B are not
      considered covered employment.  To qualify for an Award for a
      given year, an eligible employee must work in covered employment
      for more than half of that year in a single contest group and
      must have payroll activity of at least 960 hours during that
      year in that single contest group.  "Payroll activity" includes
      pay for straight time, overtime, vacation, holiday, sick leave
      and any other hourly compensation made through the payroll
      process.  The eligible groups are listed in Appendix A.  The
      definition and scope of the term "eligible employee" and other
      terms herein, without limitation, are subject to change at any
      time, at the sole discretion of the Company.

C.    SAFETY INCENTIVE AWARDS -
      1.  The Company will award 5 shares of Norfolk Southern
      Corporation common stock (as may be adjusted as appropriate by
      the Company in the event of any recapitalization, stock split
      or other change affecting the capital structure of the Company)
      to each eligible employee who (i) is a qualifying member of a
      contest team listed in Groups 1, 2, 3 or 4 of Appendix A in the
      annual Norfolk Southern Safety Performance Contest for
      Non-Operating Agreement Employees which has no reportable
      injuries for the contest year and (ii) works in covered
      employment without injury during the contest year.

      2.  The Company will award 6 shares of Norfolk Southern
      Corporation common stock (as may be adjusted as appropriate by
      the Company in the event of any recapitalization, stock split
      or other change affecting the capital structure of the Company)
      to each eligible employee who is a member of a winning contest
      team listed in Group 5 of Appendix A in the annual Norfolk
      Southern Safety Performance Contest for Non-Operating Agreement
      Employees and who works in covered employment without injury
      during the contest year.  A winning contest team in Group 5 of
      Appendix A shall be that contest team which achieves the lowest
      FRA Reportable Injury Ratio of all contest teams in its group
      during the contest year (if there is only one team listed in
      Group 5, then that team shall compete with the Group 2 Terminals
      listed in Appendix A to the Norfolk Southern Safety Incentive
      Plan for Operating Agreement Employees, for purposes of this
      Award and the additional Award described in the second sentence
      following).  In case of ties, duplicate Awards will be provided.
      The Company will also award an additional 2 shares of Norfolk
      Southern Corporation common stock (as may be adjusted as
      appropriate by the Company in the event of any recapitalization,
      stock split or other change affecting the capital structure of
      the Company) to each eligible employee who works in covered
      employment without injury during the contest year and is a
      member of a winning contest team listed in Group 5 of Appendix
      A in the annual Norfolk Southern Safety Performance Contest for
      Non-Operating Agreement Employees which achieves a FRA
      Reportable Injury Ratio of zero.

D.    WORKING WITHOUT INJURY - In order to be considered as having
      worked in covered employment without injury during a contest
      year for purposes of SIP, an eligible employee must not be
      named as being injured in an FRA-reportable accident/injury
      report during that year.  In the event that an eligible employee
      is named as being injured in any such report while employed in
      covered employment, he/she and, except as otherwise provided
      herein for winning contest teams in Group 5 of Appendix A,
      his/her contest team will not be eligible for an Award during
      the contest year.  Failure by an eligible employee to make a
      proper report of an injury during covered employment will result
      in his/her being removed from consideration for an Award in the
      calendar year in which the unreported injury occurred, and, if
      it is a different year, in the year in which the Company learns
      of the failure to make a proper report.

E.    SIP ADMINISTRATION - The SIP will be administered by the Safety
      Department.  Employee injury statistics for eligible employees
      will be maintained by the Safety Department.

F.    TERMINATION AND AMENDMENT - The Company has and reserves the
      right to terminate or amend SIP at any time and for any reason,
      in its sole discretion.

                        SAFETY INCENTIVE PLAN

                   FOR OPERATING AGREEMENT EMPLOYEES

A.   INTRODUCTION - The Norfolk Southern Safety Incentive Plan ("SIP")
     is designed to provide an additional incentive to work safely
     through Safety Incentive Awards ("Awards") to eligible agreement
     employees who work without injury during the contest period.

B.   ELIGIBILITY AND COVERED EMPLOYMENT - An "eligible employee" is
     an employee of Norfolk Southern Corporation or one of its rail
     subsidiaries or affiliates (the "Company") who works in the
     Operations Division during a calendar year a sufficient number
     of hours in "covered employment" equal to that required to earn
     vacation.  "Covered employment" is employment in a position
     covered by a collective bargaining agreement.  To qualify for
     an Award for a given year, an eligible employee must work in
     covered employment for more than half of that year in a single
     contest group and must have payroll activity of at least 960
     hours during that year in that single contest group.
     "Payroll activity" includes pay for straighttime, overtime,
     vacation, holiday, sickleave and any other hourly compensation
     made through the payroll process.  The eligible groups and
     competitive groupings are listed in the "Norfolk Southern
     Safety Performance Contest Groups," which is attached as
     Appendix A.  The definition and scope of the term "eligible
     employee" and other terms herein, without limitation, are
     subject to change at any time, at the sole discretion of
     the Company.


C.   SAFETY INCENTIVE AWARDS - The Company will award 6 shares
     of Norfolk Southern Corporation common stock (as may be
     adjusted as appropriate by the Company in the event of any
     recapitalization, stock split or other change affecting the
     capital structure of the Company) to each eligible employee
     who is a member of a winning contest team in the annual
     Norfolk Southern Safety Performance Contest and who works
     in covered employment without injury during the contest year.
     A winning contest team shall be that contest team which
     achieves the lowest FRA Reportable Injury Ratio of all
     contest teams in its group during the contest year.  In case
     of ties, duplicate Awards will be provided.  The Company
     will also award an additional 2 shares of Norfolk Southern
     Corporation common stock to each eligible employee who works
     in covered employment without injury during the contest year
     and is a member of a winning contest team in the annual
     Norfolk Southern Safety Performance Contest which achieves a
     FRA Reportable Injury Ratio of zero.

D.   WORKING WITHOUT INJURY - In order to be considered as
     having worked in covered employment without injury during a
     contest year for purposes of SIP, an eligible employee must
     not be named as being injured in any FRA-reportable
     accident/injury report during that year.  In the event that
     an eligible employee is named as being injured in any such
     report while employed in covered employment, he/she will not
     be eligible for an Award during the Contest year.  Failure by
     an eligible employee to make a proper report of an injury
     during covered employment will result in his/her being removed
     from consideration for an Award in the calendar year in which
     the unreported injury occurred, and, if it is a different year,
     in the year in which the Company learns of the failure to
     make a proper report.


E.   EXCEPTIONS - If a Department Head, after consultation with the
     Law Department, determines that an injured employee in that
     Department was not at fault and could not have avoided the
     injury, the employee's injury-free status for SIP purposes will
     be restored.  The determination made by the Department Head
     will be final and there will be no appeal.

F.   SIP ADMINISTRATION - The SIP will be administered by the Safety
     Department.  Employee injury statistics for eligible employees
     will be maintained by the Safety Department.

G.   TERMINATION AND AMENDMENT - The Company has and reserves the
     right to terminate or amend SIP at any time and for any reason,
     in its sole discretion.
