Exhibit 99.1 BULLETIN July 2, 1999 ATTENTION: All Agreement Employees Special Availability Bonus Program The month of June was particularly demanding for all of us. I sincerely appreciate all of your efforts to make the new NS work. July and August will also be challenging months. We must continue to concentrate on improving the quality of service to our customers, while maintaining our focus on safety. In recognition of the level of dedication that will be required to successfully complete the tasks at hand, the Special Availability Bonus Program, as outlined below, is being placed in effect. Effective 12:01 a.m., Saturday July 3, all agreement employees paid on a bi-weekly basis who remain marked up and available for service throughout the payroll period will receive a special bonus of $600 for each two-week period to be contributed to the employee's 401(k)account as an employer contribution (to be invested in Norfolk Southern stock or otherwise, as provided by the terms of the applicable plan). Agreement employees paid on a weekly basis who remain marked up and available for service throughout two-week consecutive payroll periods paired below also will receive $600 for each two-week period to be contributed to the employee's 401(k) account in the same manner. NS will establish a 401(k) account for those employees who qualify for the bonus and do not have an established 401(k) account. In each case, the contributions to the plan will be made after the close of the last bonus period and upon completion of corporate formalities. This program will remain in effect for the following payroll periods: Bi-Weekly July 3 - July 16 August 14 - August 27 July 17 - July 30 August 28 - September 10 July 31 - August 13 Weekly June 30 - July 6 July 14 - July 20 July 7 - July 13 July 21 - July 27 July 28 - August 3 August 11 - August 17 August 4 - August 10 August 18 - August 24 August 25 - August 31 September 1 - September 7 Weekly NY July 3 - July 9 July 17 - July 23 July 10 - July 16 July 24 - July 30 July 31 - August 6 August 14 - August 20 August 7 - August 13 August 21 - August 27 August 28 - September 3 September 4 - September 10 Being marked off prior to 12:01 a.m., July 3 will not disqualify an employee from the bonus as long as the employee marks back up for service by 12:01 a.m. on July 3. An employee scheduled to be on vacation during this period may, with the concurrence of their supervisor, receive pay for and be charged for vacation, make himself or herself available for work in lieu of vacation, and participate in this special bonus program. Employees working assignments with designated off days must be available for service on their off days in order to be eligible for this bonus. /s/ David R. Goode D. R. Goode
