The correct answer is Chinese immigrants.

Chinese immigrants made up the majority of the workforce that built the transcontinental railroad in the United States. They were recruited because of their reputation for hard work and low wages. They were also willing to work in dangerous conditions, such as blasting through mountains and laying track across treacherous terrain. An estimated 15,000 Chinese workers died during the construction of the transcontinental railroad.
