Just north of Chagny, Saône et Loire, a triangular junction gives access to rail routes to the west towards Nevers and Moulins. A double track railway passes the vineyards of Santenay and along the valley of the Dheune river and the Canal du Centre.
At Montchanin the line to Nevers branches off to the north through Le Creusot. After the smart town of Montceau-les-Mines the railway accompanies the Canal du Centre across pleasant agricultural plains to the junction at Paray-le-Monial.
This line is a strategic route linking the ex PLM main line to the Paris - Clermont-Ferrand main line.
TER services along this line include Clermont-Ferrand - Dijon and Lyon - Paray - Chalons sur Saône.
