Le Musée du train miniature in Châtillon-sur-Chalaronne isn't just a museum of miniature trains, and nor is it designed with children in mind: it's a mind-blowing experience of what can be achieved once an enthusiast (P. Crolle), indeed an obsessive person, decides to devote twenty years to a particular vision. The (often animated) models here, and they stretch from the shores of the Mediterranean, up the Rhône valley to Lyon to the Savoie country, are on a tiny but highly detailed scale. The model, which extends to 200 square metres, is fascinating.
