were hired by the Union Pacific had been employed during the American Civil War to repair and operate the over of railroad line the U.S. Military Railroad controlled by the end of the war. The Union Pacific also utilized their experience repairing and building truss bridges during the war. Most of the semi-skilled workers on the Union Pacific were recruited from the many soldiers discharged from the Union and Confederate armies along with emigrant Irishmen. After 1864, the Central Pacific Railroad received the same Federal financial incentives as the Union Pacific Railroad, along with some construction bonds granted by the state of California and the city of San Francisco. The Central Pacific hired some Canadian and European civil engineers and surveyors with extensive experience building railroads, but it had a difficult time finding semi-skilled labor. Most Caucasians in California preferred to work in the mines or agriculture. The railroad experimented by hiring local emigrant Chinese as manual laborers, many of whom were escaping the poverty and terrors of the war in the Sze Yup districts in the Pearl River Delta of Guangdong province in China. When they proved themselves as workers, the CPRR from that point forward preferred to hire Chinese, and even set up recruiting efforts in Canton. Despite their small stature and lack of experience, the Chinese laborers were responsible for most of the heavy manual labor since only a very limited amount of that work could be done by animals, simple machines, or black powder. The railroad also hired some black people escaping the aftermath of the American Civil War. Most of the black and white workers were paid $30 per month and given food and lodging. Most Chinese were initially paid $31 per month and provided lodging, but they preferred to cook their own meals. In 1867 the CPRR raised their wage to $35 (equivalent to $ in ) per month after a strike. CPRR came to see the advantage of good workers employed at low wages: "Chinese labor proved to be Central Pacific's salvation." Transcontinental route Construction begun The Central Pacific broke ground on January 8, 1863. Because of insufficient transportation alternatives from the manufacturing centers on the east coast, virtually all of their tools and machinery including rails, railroad switches, railroad turntables, freight and passenger cars, and steam locomotives were transported first by train to east coast ports. They were then loaded on ships
