Santa Fe–Southern Pacific merger

The Santa Fe–Southern Pacific merger was an attempted corporate consolidation of two of the major railroads in the Western United States at the time: the Atchison, Topeka and Santa Fe Railway and the Southern Pacific Railroad. The approximately US$5 billion deal (US$15.5 billion in 2025 dollars) was announced in September 1983 and in December 1983, both companies were acquired by a new holding company, the Southern Pacific Santa Fe Corporation and both companies' extensive non-railroad related assets were immediately combined.
