Penn Central's 1970 bankruptcy became the largest corporate bankruptcy in American history at that time.
Penn Central Transportation Company filed for bankruptcy protection on June 21, 1970. It had been created in 1968 by merging the Pennsylvania Railroad and New York Central, but the combined company quickly faced declining passenger and freight business, heavy costs, regulatory constraints, and difficulties integrating its operations.
The filing shocked financial markets because Penn Central commercial paper had been widely trusted as a short-term investment. When confidence disappeared, the commercial-paper market tightened and government officials took emergency steps to prevent a broader financial disruption.
The bankruptcy was not a conventional one-day stock-market crash like 1929 or 1987. It was a major corporate failure that exposed weaknesses in U.S. rail transportation and helped prompt later federal support and regulatory changes.
