A ligne 'normale' is probably the way forwards, especially if incorporating speeds of 160 km/h+. You will notice my choice of 'ligne normale' instead of 'ligne Classique'- this is intentional as:
I envisage a line similar to GPSO phase 2 (Dax to Spain), with 220kph operation and 160 km/h freight. The line, depuis Lyon takes a parallel route to the A43 up to Chambéry. The line then sweeps round into the Isère valley, heading towards Albertville, with a new underground station below the Olympic Stadium to eliminate the need to reverse. The trains then take a fully double-tracked and upgraded Chambéry - Bourg Saint Maurice line up to Aigueblanche, before entering a new tunnel with eased curves, emerging at Saint-Marcel (Due to gradients, goods trains still go via Moutiers). Trains now join a double-tracked Ligne Classique for the last 30/40kms into Bourg, where the new line continues to Aoste in Italy. From there, the line descends down towards Novare and eventually Milan, offering a new, faster transalpine route.
Along the route, the Gare d'Aime (with mountain railway to the ski resort Plagne 1800 seems to appeal to me.
