My search results on Trenitalia's site shows "No Travel Solution Found" in looking for trains from Pré Saint Didier to Ivrea. I know there is a line and an end station there and it runs to Aosta.
Has something changed, or is this line operated by a different company, and if so how do I find schedules?
On to the wiki page of Stazione di Pré-Saint-Didier is stated (under "Movimento")
La stazione era in ultimo servita da treni regionali di Trenitalia fino al 24 dicembre 2015, giorno in cui la linea è stata sospesa al traffico per decisione della Regione Valle d'Aosta e sostituito da autocorse.
Google translates this as
The station was finally served by regional trains Trenitalia until December 24, 2015, the day when the line was suspended traffic for decision of the Valle d'Aosta region and replaced by bus rides.
I'm afraid you'll have to take the bus.
