Support Activities for Rail Transportation

NAICS 488210 · Support Activities for Transportation · SBA size standard: $34 million average annual receipts

Rail support contractors provide switching, terminal operations, tank-car cleaning, inspection and light maintenance services for freight railroads and shippers. For a yard contractor that switches cuts of cars, cleans and inspects tank cars and performs minor repairs, the specialists turn incoming work orders into validated tasks, build daily switching and cleaning plans around mainline windows, manage locomotive and parts inventory, dispatch crews and equipment, capture inspection records and prepare billing packages. Crew qualifications, track permits, safety logs and FRA paperwork remain with the yard supervisor.

What makes this business different

  • Work orders that specify exact railcar initial and number, car type, last contents, required service and any hazards
  • Daily switching plans that must fit within railroad-published inbound and outbound windows without blocking mainline tracks
  • Coordination of switch engines, multiple crews, track assignments and cleaning tracks while maintaining clear foul time
  • Heavy equipment including switcher locomotives, vacuum trucks, pressure-washing rigs, mobile cranes and railcar movers that require daily pre-shift inspections, fuel and FRA-compliant records
  • Parts and consumables such as brake shoes, hoses, cleaning chemicals, lubricants and PPE that must be kept at yard par levels
  • FRA, OSHA, railroad-specific safety rules, track access permits, lockout-tagout, hazardous materials handling and daily inspection logs
  • Billing that references exact railcar identifiers, AAR service codes, start and stop times and supporting documentation
