Are any of the Paris-Dijon TERs still loco-hauled, or just the Paris-Laroche Migennes shuttle? The Paris-Dijon TERs were already a mixture of loco-hauled Corail sets and bi-mode units last time I travelled on that line when staying with friends near Auxerre in 2014. And of course the Laroche Migennes-Auxerre-Avalon line is worked exclusively by bi-modes.TER Gare de Lyon - Laroche-Migennes. Stops at Fontainebleau-Avon for Napoleon's Versailles
Also, at that time some of the Paris-Dijon TERs used the Gare de Lyon and some used the Gare de Bercy. I expected Bercy to be a largely all-unit station but back then there were even some loco-hauled workings out of Bercy. Not sure if there still are now.
