1950: The final run for the Pacific Electric Railway‘s Santa Ana line.
The line’s history dated back to 1903 but was completed and open for service on November 6, 1905.
The Santa Ana Line diverged from the Long Beach Line at Watts and proceeded 26.5 miles southeast to Fourth Street in Santa Ana.
Most service terminated at the Pacific Electric station there, but some continued another 2/3 mile eastward to the Southern Pacific Station.
Its peak year of service was 1945 with over 2.4 million passenger boardings.
