The Golden age of the rail network in France was probably in 1928. The standard gauge main line network had attained a length of more than 40,000km, while the secondary rail network had reached its peak at 22,000 km.
This secondary rail network, criss-crossing the countryside, and focussed on local traffic, included track at standard gauge, but, more often, at metre gauge and at 0,60 cm gauge. Between the Age of the Horse and the Age of the Motor Car, the heyday of the secondary rail network in France lasted just 30 years and by the beginning of the 1930's the lines making the most losses were closing fast.
By 1965, just 2,000 km of of such secondary lines remained in operation.
By 1985, apart from a few lines run by volunteers, the remnants of the "Blanc-Argent" metre gauge line in the departments of the Indre and Cher, was one of the very few secondary lines surviving in the public domaine.
But in 1988, a further segment of this line was lopped off, from Buzançais to Luçay-le-Mâle in the Indre.
