6. History Fund resource: Union Pacific Railroad was created by a federal charter with a capitalization of $100 million. Central Pacific Railroad was incorportated by Mark Hopkins,Leland Standford, Collis Potter Huntington, Charles Crocker.(Known as ‘Big Four’)

7. Beginning time The Central Pacific started work in 1863. Due to competition with the War for workers, rails, ties, railroad engines and supplies, the Union Pacific Railroad did not start construction until July 1865.

8. Laborers The Central Pacific's grade was constructed primarily by many thousands of emigrant workers from China. The majority of the Union Pacific track was built by Irish laborers, and veterans of both the Union and Confederate armies.

9. Construction Central Pacific The Central Pacific made great progress along the Sacramento( 萨克拉门托 ) Valley. However construction was slowed, first by the foothills of the Sierra Nevada( 内华达 ), then by the mountains themselves and most importantly by winter snowstorms. Union Pacific The progress started in Omaha, Nebraska, by the Union Pacific Railroad proceeded very quickly because of the open terrain of the Great Plains. This changed, however, as the work entered Indian-held lands.

10. The Last Spike Six years after the groundbreaking, the Central Pacific Railroad from the west and the Union Pacific Railroad from the east met at Promontory Summit( 大盐湖正北方的突顶山 ), Utah. It was here on May 10, 1869 that Stanford and Thomas C.Durant drove the The Last Spike (or golden spike)that joined the rails of the transcontinental railroad. In November 1869 the Central Pacific finally connected Sacramento to San Francisco Bay at Oakland, California.

11. Aftermath The feat is depicted in various movies, including the 1939 film Union Pacific.
