Electrical Engineering Milestone
Between July 4 and October 24, 1861, a telegraph line was constructed by the Western Union Company between St. Joseph, Missouri, and Sacramento, California, thereby completing the first high-speed communications line between the Atlantic and Pacific Coasts. This service met the critical demand for fast communications between these areas. The telegraph line operated until May 1869, when it was replaced by a multi-wire system constructed with the Union Pacific and Central Pacific railway lines.| HM Number | HMVYF |
