In 1859, the Belgian Company for the construction of railway equipment was created by merging the Charles Évrard Establishments in Brussels and Parmentiers in La Croyère. The factory in La Croyère mainly produced boilers for locomotives assembled in Brussels before production gradually shifted to La Croyère.
On September 15, 1881, the Société anonyme for the construction of railway machinery and equipment was created. In order to circumvent the very high import taxes in France, its head office moved to Paris; it has just inaugurated new factories in Raismes in France and operates in parallel that of La Croyère in Belgium. This material was exported around the world, including the Ottoman Empire, as shown in these promotional flyers.
