Which railroad was acquired by the Union Pacific Corporation and became part of one of the world's largest transportation companies?
Western Pacific Railroad The Western Pacific Railroad (reporting mark WP) was a Class I railroad in the United States. It was formed in 1903 as an attempt to break the near-monopoly the Southern Pacific Railroad had on rail service into northern California. WP's Feather River Route directly competed with SP's portion of the Overland Route for rail traffic between Salt Lake City/Ogden, Utah and Oakland, California for nearly 80 years. In 1983, the Western Pacific was acquired by the Union Pacific Corporation and it was soon merged into their Union Pacific Railroad. The Western Pacific was one of the original operators of the "California Zephyr".
Philadelphia, Wilmington and Baltimore Railroad The Philadelphia, Wilmington and Baltimore Railroad (PW&B) was an American railroad company itself a result of merger of four small lines dating from the earliest days of American railroading in the late 1820s and early 1830s, that operated from 1836, until being bought by a larger regional line in 1881, with a merger into a longer Northeast Corridor railway in 1902. It built the first rail line south from Philadelphia into The South.
