The Terre Haute and Alton railroad built the first bridge over the Wabash  River in 1855.  The name changed to Terre Haute, Alton and St Louis Railroad in 1856 and changed again to St Louis, Alton and Terre Haute Railroad in 1862.  This existed until at least 1876 and was acquired by the Vanderbilts in the  mid 1880's.

The railroad was formed on June 30, 1889 by the merger of the Cleveland, Columbus, Cincinnati and Indianapolis Railway, the Cincinnati, Indianapolis, St. Louis and Chicago Railway and the Indianapolis and St. Louis Railway.

The Chicago and North Western Railway was chartered on June 7, 1859, five days after it purchased the assets of the bankrupt Chicago, St. Paul and Fond du Lac Railroad. On February 15, 1865, it merged with the Galena and Chicago Union Railroad, which had been chartered on January 16, 1836. Since the Galena & Chicago Union started operating in December 1848, and the Fond du Lac railroad started in March 1855, the Galena and Chicago Union Railroad is considered to be the origin of the North Western railroad system.

The Grand Rapids and Indiana Railroad at its height provided passenger and freight railroad services between Cincinnati, Ohio, and the Straits of Mackinac in Michigan, USA. The company was formed on January 18, 1854.

The Great Western Railway, a Canadian company, had taken financial control of the D&M in 1860 after it defaulted on debt payments. The D&M entered receivership in 1875; in 1878 Great Western purchased it outright and refinanced the debts.

The Pere Marquette Railroad was incorporated on November 1, 1899, in anticipation of a merger of three Michigan-based railroad companies[1] that had been agreed upon by all parties. It began operations on January 1, 1900, absorbing the following companies:

The Delaware and Hudson Railway (D&H) (reporting mark DH) is a railroad that operates in the Northeastern United States. In 1991, after more than 150 years as an independent railroad, the D&H was purchased by the Canadian Pacific Railway (CP).

The Shamokin Valley and Pottsville had been commenced in 1835 to transport coal from the mines to the Susquehanna Canal at Sunbury and was extended to Mt. Carmel in 1854.
