The U.S. Department of Transportation agency responsible for railroad safety regulation and enforcement, including track standards, equipment inspection, operating rules, and hazardous materials transportation. The FRA conducts safety inspections, investigates accidents, and issues emergency orders when immediate safety threats exist. It also administers federal rail investment programs.
The independent U.S. federal agency responsible for the economic regulation of the nation's freight railroads, including jurisdiction over rates, mergers, acquisitions, line sales, and abandonments. The STB was created by the ICC Termination Act of 1995 as the successor to the Interstate Commerce Commission. It adjudicates shipper complaints about unreasonable rates and competitive access.
The U.S. DOT agency that regulates the safe transportation of hazardous materials by rail, highway, air, and pipeline. PHMSA sets specifications for tank car construction, placarding requirements, and emergency response standards. It works jointly with the FRA on railroad hazmat incidents.
A safety system mandated by Congress after the 2008 Chatsworth collision that automatically enforces speed limits, prevents train-to-train collisions, and enforces temporary speed restrictions, overriding human error. PTC uses GPS, wireless communications, and digital track maps to monitor and control train movements in real time. All Class I railroads completed PTC implementation by the 2020 deadline.
Materials designated by PHMSA as posing a risk to health, safety, property, or the environment during transportation, including explosives, flammable liquids, poisonous gases, and radioactive materials. Hazmat shipments require proper classification, packaging, marking, labeling, placarding, and documentation under 49 CFR. Railroads have specialized procedures and routing requirements for hazmat movements.
A formal directive issued by the FRA requiring railroads to take specific safety actions across their operations, such as inspecting a class of equipment, restricting train speeds, or implementing new operating procedures. General orders have the force of law and must be complied with immediately. They are typically issued in response to safety findings from accident investigations or inspection programs.
