I’m checking on making train reservations using the oui.sncf app for Paris to Rouen on New Year’s Day.
Booking two senior tickets from Paris to Rouen on Jan 1, I see DIRECT TER and DIRECT TRAIN NOMAD available at multiple times during the day.
TER has 2nd class at 24.10 each and 1st class at 36.10 each. Both are non-refundable and non-exchangeable.
NOMAD has cheaper and less restrictive options: 2nd class 11.50 each and 1st class 15.50 each, with both being exchangeable. And there is an option for 2nd class (modifiable free of charge) for 24.10 each.
QUESTIONS: What is the difference between Nomad and TER? Is TER much better to justify the higher, more restrictive fare?
In light of the current rail strikes, what do you recommend?
