About 4 out of 10 TGV and Intercity trains were running on Saturday, and unions have warned passengers of further cancellations.
Unions have also filed a strike notice for the Christmas and New Year's weekends.
The almost 10,000 SNCF conductors, of which nearly 3,000 work on the TGV and Intercity trains, work to maintain traffic and passenger safety. Trains cannot run without them.
SNCF management has announced that there will be "new meetings" with trade unions and workers next week.
