Chemin de Fer du Nord

The Chemins de Fer du Nord (French: Compagnie des chemins de fer du Nord or CF du Nord), (English: Northern Railway Company) often referred to simply as the Nord company, was a rail transport company created in September 1845, in Paris, France. It was owned by among others de Rothschild Frères of France, N M Rothschild & Sons of London, England, Hottinger, Laffitte and Blount.Baron James de Rothschild served as the company's first president from its inception until his death in 1868.

A royal ordnance dated 10 September 1845 granted exploitation of the railway from Paris to Lille and Valenciennes, branch lines to Dunkirk and Calais and two new lines Creil - Saint-Quentin and Fampoux - Hazebrouck to the CF du Nord. From the Gare du Nord station the company built in Paris, the Paris–Lille railway line led north towards Belgium, first connecting in 1846 to Amiens, Douai and Lille, with a branch line from Douai to Valenciennes. Lille and Valenciennes had already been connected to the Belgian railway network in 1842. The new line made it possible to travel by train from Paris to Brussels and further.

In the following years, the network was rapidly expanded:

The potential for expansion of the CF du Nord territory was limited by other companies: the Chemins de fer de l'Ouest to its southwest, and the Chemins de fer de l'Est to its east. By opening a line to from Paris to Hirson via Soissons and Laon from 1860 to 1871, it protected its eastern border against CF de l'Est expansion. The concession for the line from Creil to Beauvais, owned by CF de l'Est predecessor Chemins de fer des Ardennes, was exchanged for the Nord's concession for Laon–Reims in 1855.
