In our many trips to Nice and Les Alpes Maritimes, my wife and I have seen a significant amount of engineering works, bridges, viaducts and tunnels all on lines which were neither part of the PLM network of standard gauge railways, nor part of the general metre-gauge network. It turns out that there were a significant numbe of line operated by tow main tramway companies in Provence, Tramways de les Alpes Maritime (TAM) and tramways de Nice et du Littoral (TNL).
These tramways ran on metre-gauge tracks but had a loading gauge not much wider than the track-gauge. In many places they ran alongside roads or withing the highway itself, but often they deviated away from the highway or their own formation.
The one which first drew our attention was the Sospel to Menton Tramway which was operated by the TNL. This is the story:
