climb and descent between Saint-Denis and Creil could be avoided. The arrival of stronger engines prompted the CF du Nord to construct a 19 km shorter line between Saint-Denis and Creil over the plateau, passing along Chantilly. This new section was opened on 10 May 1859. Since the opening of the LGV Nord high speed line between Paris and Lille in 1993, most long-distance passenger traffic has shifted away from the classical Paris–Lille line. It remains an important railway for freight traffic and regional passenger traffic.
