The Central Pacific track was constructed primarily by Chinese immigrants. Even though at first they were thought to be too weak or fragile to do this type of work, after the first day in which Chinese were on the line, the decision was made to hire as many as could be found in California (where most were gold miners or in service industries such as laundries and kitchens). Many more were imported from China. Most of the men received between one and three dollars per day, but the workers from China received much less. Eventually, they went on strike and gained small increases in salary.
