National Park Service unit at Promontory Summit marking the 10 May 1869 completion of the first transcontinental railroad. Restored grade, replica Jupiter and No. 119 locomotives, engine house, and interpretive trails on the sagebrush bench above the Great Salt Lake desert. Thin-county northern Utah stop that anchors Western railroad history rather than red-rock scenery.
