 On 14 July 1984, after pressure from several municipalities and inhabitants of the Manche département, the association increased its interest to the preservation of all local railways in the Manche and became "Association pour les Transports en Commun de la Manche" (ATCM).In July, as a promoter of tourism in the region, it changed once more its name to "Association Tourisme et Chemins de fer de la Manche".From 21 December 1988 to 30 June 1994, the Train Touristique du Cotentin ran trains on a 10 km section of track from Carentan to Baupte with a 1950s railcar, then the X3825, the X2426.
