Between 1865 and 1869, thousands of Chinese migrants toiled at a grueling pace and in perilous working conditions to help construct America’s First Transcontinental Railroad. The Chinese Railroad Workers in North America Project seeks to give a voice to the Chinese migrants whose labor on the Transcontinental Railroad helped to shape the physical and social landscape of the American West. The Project coordinates research in the United States and Asia in order to create an on-line digital archive available to all. The Project is also organizing major conferences and public events at Stanford and in China in 2015 to commemorate the 150th anniversary of the arrival of large numbers of Chinese to work on the railroad. In collaboration with the Spatial History Project, we are producing visualizations and maps that help us understand how Chinese railroad workers contributed to shaping not just the physical but the social landscape of the West.
