LA Rail History
From Red Cars to Metro Rail
Los Angeles has operated rail transit in three distinct eras. The first, from 1874 to 1961, was dominated by the Pacific Electric Railway—the "Red Cars"—a 1,600-mile interurban network that connected 55 communities across four counties. Its decline, accelerated by freeway construction and changing land-use patterns, left the region car-dependent for three decades.
The modern era began on July 14, 1990, when the Metro A Line (Blue Line) opened as California's first modern light rail segment. The Metro B Line (Red Line) subway followed in 1993, built under the oversight of the Los Angeles County Transportation Commission (LACTC). Today, LACMTA operates eight rail lines, with major extensions under construction for the 2028 Olympics.
