The busiest section is Moisenay junction to Pasilly junction (e.g. the end of the Interconnexion to the branch-off towards Dijon). I looked up Monday and direction away from Paris (Gare de Lyon/Massy/CDG). Between 15:50 and 20:00, I counted 46 trains (may have missed some).
Minimum headway was 5 minutes on the old units with old signalling, it's now 3 minutes with the TVM 430. But scheduled times usually alternate between 4 and 6 min, only sometimes down to the 3 min minimum. Yet this is not being generous with time: you need some buffer for lateness, and if the previous train has one more stop, then the next non-stop train must leave a longer buffer for the first train to accelerate back.
So with view to this, between these 46 trains from 15:50 and 20:00, I found just six empty slots (had they been used by trains from Gare de Lyon: 16:14, 16:34, 16:40, 19:34, 19:50, 19:54). And those slots will certainly be filled up once the TGV Rhin-Rhône and the line to Turin are built. Pretty close to saturation. *Lunatic*, n. One whose delusions are out of fashion.
However, how is TGV Rhin-Rhône supposed to feed that branch? Un roi sans divertissement est un homme plein de misères
Though, it is just the Ouest branch that'll be built last, and until then, Mulhouse will also get access from Paris via Strasbourg, so maybe there won't be much of a frequency increase via Dijon when the first leg opens (2011?). *Lunatic*, n. One whose delusions are out of fashion.
