Having just enjoyed a holiday in the Languedoc near Ollargues, I became conscious of the former railway line between Mazamet and Bedarieux which is now a 'voie verte' used for walking and cycling. Apart from finding out it closed to passengers in 1972 and freight in the late 80s, can anyone suggest any books or other sources of historical information on the line (doesn't matter if in French).   The former station in Ollargues, now a garage and post office:     The iron bridge at Ollarg
