This association of volunteers (founded in 1995) preserves and maintains the service of the historical vehicles of the Martigny-Châtelard railway.
It owns a collection of vehicles dating from between 1905 and 1921. These historical trains can only run between Martigny and Vernayaz. Every year, it organises a “retro” weekend open to the public (train and bus), in principle during the last weekend in October. It offers, on demand, transport by historic trains for private groups, with an aperitif and visit to the depot in Martigny.
