The Mount Lowe Railway was the third in a series of scenic mountain railroads in the United States created as a tourist attraction on Echo Mountain and Mount Lowe, north of Los Angeles, California. The railway, originally incorporated by Thaddeus S. C. Lowe as the Pasadena and Mt. Wilson Railroad Co., existed from 1893 until its official abandonment in 1938, and was the only scenic mountain, electric traction (overhead electric trolley) railroad ever built in the United States. Lowe's partner and engineer was David J. Macpherson, a civil engineer graduate of Cornell University. The Mount Lowe Railway was a fulfillment of 19th century Pasadenans' desire to have a scenic mountain railroad to the crest of the San Gabriel Mountains.
