The First Transcontinental Railroad (also called the Great Transcontinental Railroad, known originally as the "Pacific Railroad" and later as the "Overland Route") was a 1,912-mile (3,077 km) continuous railroad line constructed between 1863 and 1869 that connected the existing eastern U.S. rail network at Omaha, Nebraska/Council Bluffs, Iowa with the Pacific coast at the Oakland Long Wharf on San Francisco Bay.[1] The rail line was built by three private companies over public lands provided by extensive US land grants.[2] Construction was financed by both state and US government subsidy bonds as well as by company issued mortgage bonds.[3][4][5][N 1] The Western Pacific Railroad Company built 132 mi (212 km) of track from Oakland/Alameda to Sacramento, California. The Central Pacific Railroad Company of California (CPRR) constructed 690 mi (1,110 km) eastward from Sacramento to Promontory Summit, Utah Territory (U.T.). The Union Pacific built 1,085 mi (1,746 km) from the road's eastern terminus at Council Bluffs near Omaha, Nebraska westward to Promontory Summit.[7][8][9]
The railroad opened for through traffic on May 10, 1869 when CPRR President Leland Stanford ceremonially drove the gold "Last Spike" (later often referred to as the "Golden Spike") with a silver hammer at Promontory Summit.[10][11] The coast-to-coast railroad connection revolutionized the settlement and economy of the American West. It brought the western states and territories into alignment with the northern Union states and made transporting passengers and goods coast-to-coast considerably quicker and less expensive.
Paddle steamers linked Sacramento to the cities and their harbor facilities in the San Francisco Bay until 1869, when the CPRR completed and opened the WP grade (which the CPRR had acquired control of in 1867–68 [N 2][N 3]) to Alameda and Oakland.
The first transcontinental rail passengers arrived at the Pacific Railroad's original western terminus at the Alameda Mole on September 6, 1869 where they transferred to the steamer Alameda for transport across the Bay to San Francisco. The road's rail terminus was moved two months later to the Oakland Long Wharf about a mile to the north.[15][16][N 4] Service between San Francisco and Oakland Pier continued to be provided by ferry.
The CPRR eventually purchased 53 miles (85 km) of UPRR-built grade from Promontory Summit (MP 828) to Ogden, U.T. (MP 881), which became the interchange point between trains of the two roads. The transcontinental line was popularly known as the Overland Route after the principal passenger rail service that operated over the length of the line until 1962.[19]
Answer:
It ruled against Dred Scott and set aside the Missouri Compromise and popular sovereignty.
Explanation:
The case Dred Scott v. Sanford argued whether a slave can obtain his freedom when he step on a state that make slavery illegal.
It happened in 1857. At that time, Dred Scott's (A slave) was taken by his owner from Missouri to Illinois. (According to Missouri compromise, It is still legal to own slaves in Missouri but It is Illegal to do so in Illinois).
Scott tried to make his case to the court stating that as soon as he entered Illinois, his status as a slave should be voided and he should be considered as a citizen.
At that time, The Missouri supreme court ruled against Scott's plead. The court stated that he could never be a citizen since citizenship only apply to white people. So he's still a slave no matter where his slave owner took him.
