The founding of the small historical railroad and ranching town of Livingston is a direct result of the Northern Pacific Railway (NPR). This site became a centralized point in the Rocky Mountains and the NPR's location for railroad shops to service their steam trains before ascending the Bozeman Pass, the line's highest point, located immediately west. Livingston also became the first gateway town to America's first national park, Yellowstone, which the NPR promoted heavily to visitors from the East. The NPR also operated a branch line running 50 miles (80 km) south through Paradise Valley, first to Cinnabar station and later to Yellowstone's north entrance in Gardiner. Livingston remains a historical site as part of the Lewis and Clark Expedition with Sacajawea.
