Norfolk Southern's Suppliers Performance

Track Maintenance – Of the 36,119 total miles of track we operate, we are responsible for maintaining 28,957 miles, with the remainder being operated under trackage rights from other parties responsible for maintenance.

Over 82% of the main line trackage (including first, second, third, and branch main tracks, all excluding rail operated pursuant to trackage rights) has rail ranging from 131 to 155 pounds per yard with the standard installation currently at 136 pounds per yard.

Microwave System – Our microwave system, consisting of approximately 6,968 radio route miles, 421 core stations, 30 secondary stations, and five passive repeater stations, provides communications between most operating locations. We use the microwave system primarily for voice communications, VHF radio control circuits, data and facsimile transmissions, traffic control operations, and AEI data transmissions.

Traffic Control – Of the approximately 16,500 route miles we dispatch, about 11,025 miles are signalized, including 8,200 miles of centralized traffic control (CTC) and 2,825 miles of automatic block signals. Of the 8,200 miles of CTC, approximately 6,836 miles are controlled by data radio originating at 336 base station radio sites.

Computers – A computer network consisting of a centralized production and backup data center near Atlanta, Georgia, and various distributed computers throughout the company connects the yards, terminals, transportation offices, rolling stock repair points, sales offices, and other key system locations. Operating and traffic data are processed and stored to provide customers with information on their shipments throughout the system. Computer systems provide current information on the location of every train and each car on line, as well as related waybill and other train and car movement data. In addition, our computer systems assist us in the performance of a variety of functions and services, including payroll, car and revenue accounting, billing, sourcing, inventory management activities and controls, and special studies.
