[RAILROAD]. Semi-Weekly Telegraph. Union Pacific Railroad advertisement in Ogden where golden spike was driven. Ogden City, UT, 2 July 1869. 4pp., large folio, old folds, some fading to type, penciled notation in upper margin (“Historian’s Office”). The “Golden Spike” refers to a ceremonial final spike driven into the First Transcontinental Railroad in the United States, connecting the Central Pacific and Union Pacific railroads. This historic event took place on May 10, 1869, at Promontory Summit, north of the Great Salt Lake in Utah. The Central Pacific, which had been building eastward from California, and the Union Pacific, coming westward from Nebraska, met at Promontory Summit, marking the completion of the first continuous railroad line across the continent. To celebrate this significant achievement and the joining of the two railroads, a special ceremonial final spike was made of gold.
