La Mer de Sable announced on social media they are building a Mine Train - presumably - for this year.
Although no year is mentioned in this post, the French park made an allusion to the ride in its New Year wishes post. That January 2nd post claimed guests will "roll over gold" ("rouler sur l'or" in French, metaphorically meaning getting conspicuously wealthy).
La Mer de Sable is located a little over an hour north of Paris - not too far away from Parc Astérix.
