The Central Pacific Railroad that started in California, and soon after the firsts tracks were laid, many of the crew members ran off to Nevada where silver mines were newly discovered. Because of this, constructions came to a rapid halt. Charles Crocker, the head of construction, hired 50 Chinese workers out of desperation. Crocker didn't think that they would be able to do much heavy work, however they surprised him. They could just as much and sometimes more than any other crew. He was so impressed that he sent agents to China to recruit more young men capable of hard work. When the agents arrived, the Chinese were in poverty and debt and were looking for a way out, and jumped on the offer to go to America to build railroads. Most wanted to return to China as wealthy men. More than 12,000 Chinese laborers worked for the Central Pacific. Many of the Chinese lost their live to explosions, and many other accidents. Although the Central Pacific lost many crew members they laid up to 10 miles of track per day. On May 10, 1869, the two lines came together in Utah Territory at the Promontory Summit. The Chinese were not recognized for the years of hard work they put in on the railroads. Most lost their jobs and then stayed in the United States to work on farms and start new businesses in the West. The networks of railroads would bring new settlers, encourage the construction of new towns and cities, and allow for mail and supplies to be shipped clear across the country.
