Chicago and North Western Railway Company.

"The Chicago & North Western Railway, created during the late 1850s by the merger of several small railroads in Illinois and Wisconsin, was led during its early years by William B. Ogden, Chicago's first mayor. In 1864, the Chicago & North Western absorbed the Galena & Chicago Union, which in 1848 had been the city's first railroad. Between 1872 and 1910, under the leadership of Marvin Hughitt, the length of track in the road's rail network grew from about 1,400 miles to nearly 10,000 miles. The railroad served areas concentrated in Illinois, Wisconsin, Iowa, and Minnesota. Although the company went bankrupt during the Great Depression, it survived into the second half of the twentieth century In 1968, it absorbed the Chicago Great Western, a smaller competitor. That same year, the transportation company became part of a conglomerate, Northwest Industries; four years later, the railroad was spun off and sold to its employees, becoming the Chicago & North Western Transportation Co. In 1986, when the railroad's annual revenues were nearly $1 billion, it became known as CNW Corp. It finally ceased to exist as an independent railroad in 1995, when it was bought by another old railroad company, the Union Pacific Corp"--Encyclopedia of Chicago.
