The Interstate Commerce Commission (ICC) was the first independent US government regulatory agency, established by the Interstate Commerce Act of 1887. Throughout its history, until it was abolished in 1994, the Commission was primarily involved in the regulation of the railroad industry in the United States. By 1910, concerns over railroad safety prompted Congress to amend the Act to require railroad companies to report to the Commission on accidents and incidents occurring on their lines. In addition, the Commission was tasked with investigating certain accidents for the purpose of increasing safety. In 1911, the Chief Inspector of Safety Appliances began to issue, often in the form of memoranda to the Commission, reports of these special investigations. This web site contains annotated transcriptions of these ICC accident investigation reports.
