> While the transcontinental Railroad enjoyed wide support—from President Abraham Lincoln, Congress and business leaders and investors—finding enough workers among America’s white laboring class to undertake the grueling and hazardous work proved challenging. Many Irish immigrants and other white laborers who moved west chose instead to pursue farming or mining.

I keep finding references that they utilized the Chinese because whites wouldn't do the work and the Irish mostly stayed in the east, but nothing specific about the Chinese labor being quite so directly *imported* by the employers. If you have any info on that please send it my way
