Inside the Vault: Building the Transcontinental Railroad


The transcontinental railroad transformed America. As the largest engineering project of its time, the railroad was critical for connecting the country coast to coast, and required arduous manual labor. While initially barred from hire, Chinese workers became crucial to the effort, ultimately making up 90 percent of the Central Pacific Railroad’s workforce. We will feature photographs of the completion ceremony in May 1869, where workers and engineers celebrated side by side.

Join us on June 5, 2025, from 7:00 to 8:00 p.m. ET (4:00 p.m. to 5:00 p.m. PT) when our curators discuss the construction of the transcontinental railroad with Stanford University professor Gordon H. Chang.
