The Froissy Dompierre Light Railway (CFCD) is a 600 mm (1 ft 11 5⁄8 in) narrow gauge light railway running from Froissy (a hamlet of La Neuville-lès-Bray) to Dompierre-Becquincourt, through Cappy, in the Somme department, France. It is run as a heritage railway by APPEVA (Association Picarde pour la Préservation et l'Entretien des Véhicules Anciens) and is also known as P'tit Train de la Haute Somme. It is the last survivor of the 600 mm (1 ft 11 5⁄8 in) narrow gauge trench railways of the World War I battlefields.
