What railroad for which Oakes Ames is credit as being the single most important influence in building was caught up in the  Crédit Mobilier scandal?
Oakes Ames Oakes Ames (January 10, 1804 – May 8, 1873) was an American manufacturer, capitalist, and member of the United States House of Representatives from Massachusetts. As a congressman, he is credited by many historians as being the single most important influence in the building of the Union Pacific portion of the transcontinental railroad. He is also noted for the subsequent scandal that alleged the improper sale of stock of the railroad's construction company.
Virginian and Ohio The Virginian and Ohio is both the name of a fictional railroad company created by W. Allen McClelland and the HO scale model railroad he built featuring this railroad. The V&O is famous in the model railroading world for setting a new standard for freelanced (fictional) model railroads designed to operate in a prototypical manner and was a major influence upon many model railroaders of the time. In 1984, Mr. McClelland wrote a detailed guide to the construction and operation of the railroad.
