C. Vanderbilt, a small bit I found for ya trainfag:

Atlantic and Pacific Steamship Company

gold rush years: Accessory Transport Company

By the 1850s he had turned his attention to railroads, buying up so much stock in the New York and Harlem Railroad that by 1863 he owned the line. He later acquired the Hudson River Railroad and the New York Central Railroad and consolidated them in 1869. When he added the Lake Shore and Michigan Southern Railroad in 1873, Vanderbilt was able to offer the first rail service from New York City to Chicago.
