Advance notice of SNCF engineering disruptions?

Dear all
I’m sure I should know this, but: is there a website or ?? which gives advance notice of engineering disruptions to SNCF.

We’re considering going to Paris for a long weekend at Christmas but the SNCF doesn’t give any train times for Caen-St Lazare. Earlier in December it shows trains routed to other Paris stations, with much longer journey times.

TIA

Another reason trains don’t show up when you try to book is that they are already full.
