Pacific Electric Interurban Service Begins

July 19, 1903, saw the Pacific Electric Railway commence operations on its Pasadena Short Line, connecting Los Angeles to Pasadena with fast electric cars. Founded by Henry Huntington, this system pioneered extensive interurban networks using advanced overhead electrification and multiple-unit control. It overcame mountainous terrain with innovative grading and trestles. The service transformed regional travel, enabling suburban growth and carrying millions of passengers annually at speeds up to 60 mph. Linked to broader U.S. electrification trends, it influenced city planning and remained a model for light rail until the mid-20th century. Its legacy endures in modern Los Angeles Metro lines.
