CSX technology outage halts Class I interchanges and disrupts intermodal freight

· Logistics · United States

CSX suffered a technology outage that halted interchanges with other Class I railroads and disrupted intermodal freight, the railroad said. Some systems were gradually returning to service, but significant operational restrictions remained as of Wednesday. The outage began Tuesday, and CSX determined it was not caused by a cyberattack. Because Class I interchange traffic feeds intermodal and carload networks across North America, the stoppage rippled through rail freight connections beyond CSX's own network. The railroad did not detail which systems were affected or how much traffic was delayed. Shippers relying on rail for inland container moves face knock-on delays while CSX restores full operations.

Why it matters：Class I railroads are the backbone of inland container movement, so an interchange outage at CSX can cascade into intermodal delays across North America and highlight rail operators' dependence on IT systems.

Key points

  • Outage began Tuesday and was determined not to be a cyberattack.
  • Interchanges with other Class I railroads were halted.
  • Some systems were returning to service, but restrictions remained.
