Short Line Railroads

NAICS 482112 · Rail Transportation · SBA size standard: 1,500 employees

Short line railroads operate local freight routes, interchange with Class I carriers, and manage car movements, track maintenance and customer shipments. Specialists turn customer requests into switching plans, build daily switch lists and manifests, schedule track work around train movements, track car locations and repairs, and prepare interchange paperwork while the railroad team handles all safety, mechanical inspections and FRA compliance decisions.

Workflows

Customer car order intake

Starts when: A customer requests empty or loaded car placement by phone, email or EDI

  3. Confirm against the daily switching schedule and Class I connection windows
  4. Create a placement task and draft confirmation to the customer
  5. Add the order to the next available switch list

Watch for: Specific siding lengths and weight limits must be respected; Hazardous materials require special routing and documentation
