SNCF Réseau offers the public, in particular young people in training, a tour of the Dinan-Lamballe track renovation site guided by the managers of the operation. This is an opportunity to learn more about the specific trades of construction and maintenance of railways that SNCF Réseau offers by experiencing the regeneration of the railway heritage over time by taking the example of this line opened in 1879 to linking Brittany to Normandy.
