## Summary

The National Park Service page for Golden Spike National Historical Park describes the park at Promontory Summit, Utah, where the Central Pacific and Union Pacific railroads met and the first transcontinental railroad was completed.

## Useful Claims

- Golden Spike National Historical Park preserves and interprets the Last Spike Site and railroad construction features at Promontory Summit.
- NPS frames the completion of the first transcontinental railroad as one of the great technological achievements of the nineteenth century.
- The site includes original railroad grade, construction features, and Victorian-era replica locomotives.
- NPS provides the official park identity, location, visitor context, and history-and-culture entry point for the Golden Spike story.
- The official page is a stable first citation for the park and should be paired with labor-history sources for Chinese, Irish, Latter-day Saint, and other worker contributions.

## Reliability Notes

This is the official federal park source and is strong evidence for the site's public interpretation and preservation status. It is not sufficient by itself for labor history, Indigenous dispossession, financing, or railroad-company chronology.
