My wife and I are spending a week or so in a village to the southwest of Carcassonne in France during September 2018. A little bit of research highlighted the existence of a network of metre-gauge tramways in the Aude. These tramways were only in operation for a few decades in the early part of 20th Century. Other matters will take priority during much of the time that we are in the department but I am interested in these lines and have pulled together a blog which gives an overview of the lines and which is based around a French Wikipedia article about the lines. http://rogerfarnworth.com/2018/08/27/tramways-de-laude-overview-part-1 The plan is to look at the different lines in turn in future posts.
