Visible remains of the historic line are still easily located—hundreds of miles are still in service today, especially through the Sierra Nevada Mountains and canyons in Utah and Wyoming. While the original rail has long since been replaced because of age and wear, and the roadbed upgraded and repaired, the lines generally run on top of the original, handmade grade. Vista points on [[Interstate 80]] through California's Truckee Canyon provide a panoramic view of many miles of the original Central Pacific line and of the [[snow shed]]s which made winter train travel safe and practical.

In areas where the original line has been bypassed and abandoned, primarily because of the [[Lucin Cutoff]] re-route in Utah, the original road grade is still obvious, as are numerous cuts and fills, especially the [[Big Fill]] a few miles east of Promontory. The sweeping curve which connected to the east end of the Big Fill now passes a [[Thiokol]] rocket research and development facility.

In 1957, Congress authorized the Golden Spike National Historic Site, which was redesignated the [[Golden Spike National Historical Park]] in 2019.<ref>{{cite news |last=Williams |first=Carter |date=March 19, 2019 |title=Golden Spike becomes Utah's first national historic park.
