The most repeated story about Chinese railroad labor shows workers lowered over a cliff in woven baskets to drill a ledge for the Central Pacific, and historians cannot confirm it. By 1867 Chinese workers were 80 to 90 percent of the workforce, and at Summit Tunnel they handled nitroglycerin mixed on site, a compound white crews largely refused. The episode lays out three competing scholarly positions on the basket legend.
No construction-era document describes suspended workers at Cape Horn; skeptics conclude no such work occurred, while the Stanford project treats rope work as plausible but the iconic basket image as unproven.
