Guignicourt–Rethel railway
The Guignicourt–Rethel railway was a  long narrow gauge and metre gauge railway in the north of France, commissioned in 1904/05. Three sections were closed in 1940, 1947 and 1961, while the remainder was re-gauged in 1971 and operated as a standard gauge railway until 1987. History 
The Guignicourt–Neufchâtel section of the secondary railway line of the Chemins de fer de la banlieue de Reims with a track gauge of 1000 mm was opened in 1904 and extended to Rethel in 1905. The Évergnicourt-Vieux-lès-Asfeld section was closed in 1940, the Vieux-lès-Asfeld-Asfeld section in 1947 and the Asfeld-Rethel section finally in 1961. Only the remaining Guignicourt-Evergnicourt section was converted to standard gauge in 1917 and operated until 1987. Rail track 
Vignol rails with a weight per metre of 25 kg/m on wooden sleepers were used for the superstructure of the Rethel-Asfeld line, while Vignol rails with a weight per metre of 22 kg/m on wooden sleepers were used for the neighbouring Asfeld-Dizy metre-gauge line of the Chemins de fer départementaux des Ardennes, which opened in 1909.
