Paris's former Chemin de fer de Petite Ceinture, also colloquially known as La Petite Ceinture, was a circular railway built as a means to supply the city's fortification walls, and as a means of transporting merchandise and passengers between Paris' major rail-company stations. Beginning as two distinct 'Ceinture Syndicate' freight and 'Paris-Auteuil' passenger lines from 1851, these lines formed an arc that surrounded the northern two thirds of Paris, an arc that would become a full circle of rail around the capital when its third Ceinture Rive Gauche section was built in 1867.
