Denfert-Rochereau station

Gare de Denfert-Rochereau is a railway station in Paris. It was one of the first stations of the French railway network, and is still in use as a station of Paris' RER line B.The station was built from 1842 and opened on 7 June 1846 as the Gare d'Enfer , after the nearby Place d'Enfer , itself named after the Barrière d'Enfer. The station building had a circular shape as it possessed a rail loop. Indeed, the station was the Parisian terminus of a line from Sceaux. The Ligne de Sceaux used the Arnoux system , as it required the construction of specific engines capable of travelling on very tight curves and broad gauge tracks of 1,750 mm . The Arnoux system was abandoned in 1891 and the line was converted to 1,435 mm gauge. The line was extended to Luxembourg station in 1895, with the newly created Port-Royal station along the way. At the same time, the station was renamed after Pierre Philippe Denfert-Rochereau. The line was operated by the Chemin de Fer de Paris à Orléans until 1937 when the Compagnie du Chemin de Fer Métropolitain de Paris took over. It became line B of the RER in 1977 on being extended to meet line A at Châtelet – Les Halles.
