Enhanced Railway Network Analysis

Problem Statement:

  • A topologically accurate 1:100K rail network is needed for detailed routing and infrastructure analysis.

Technical Approach:

  • ORNL has worked with an NGA-enhanced FRA 1:100K rail network to include proper interconnections between rail lines, interchange locations between railroad companies, and updated rail attributes. Status of each segment (main line, industrial spur, siding, yard track, other track, out-of-service, abandoned, physically removed, or trail) is included.


  • The ORNL 1:100K rail network provides “real world” rail capabilities for routing and infrastructure analysis.
