The Inter-California Railway, known in Spanish as the Ferrocarril Inter-California, also known as the Inter-Cal, is a former railroad line which connected the Californias by train. It operated between the American state of California and the Mexican state of Baja California.
Souther Pacific was later acquired by Union Pacific. Inter-Cal's line from Niland to Calexico remains in operation as UP's Calexico Subdivision, interchanging with Ferromex at the US-Mexico borer.
