I'm trying to make a seat reservation using Eurail Pass from Paris to Bayeux on July 8 and a return on July 12 on TER trains. (And yes, I bought the pass after consideration of all the routes we would be on over a 5 week journey in multiple countries. It's definitely going to pay off.)
The train is labeled as a TER. My original research showed - from the Man in Seat 61 (the best!) - this: TER regional, local & suburban trains, no reservation needed. This includes all TER (Trains Express Régionaux), Paris suburban trains, and all other local trains. No reservation is necessary or even possible, the train can never sell out, and the fare is fixed so there's no price advantage in pre-booking. Simply buy a ticket at the station ticket office or from the self-service machines, you may still need to validate it (composter) in the little yellow machines on the platform, hop on the next train and sit where you like.
However, I was using the Eurail site just to look at train times and noticed that every train had a note on the first leg of the July 8 journey (out of Paris) and the last leg of the July 12 journey (back to Paris) that said that we needed a seat reservation and that it was not possible to make one on Eurail's site. Nor was it possible on SNCF or any other site that my research led me to.
After digging around on Man in Seat 61, I found this tidbit on another page: Train Nomad: This is a brand name used for mainline trains between Paris & Normandy, such as Paris-Caen-Cherbourg, Paris-Rouen-Le Havre. Seat reservation is compulsory, €10. Confusingly, as they're operated by the Normandy region they are shown as TER in some ticketing systems/timetables.
So, first posting this in case others weren't aware that you do need reservations on some TER trains, but next is my question: it seems that my choices are to buy the full fare ticket on SNCF and not use the pass (we'll be coming from Bruges via Brussels so it will not be just a short journey on the pass and I have enough days available) or to wait till I get to the station to buy the reservation using the kiosk and the pass. Since the Man in Seat 61 says that the trains can never sell out, it seems like the second option is good, but that makes the planner in me nervous.
Has anyone done this: made reservations the day of travel in Paris on a busy July Saturday?
Or are there any other countries in which I can find the SNCF kiosks or offices in which to buy the reservation during my journey and take care of the reservation earlier? We will be in London, Amsterdam, many places in Germany, and Poland (not in that order) before Bruges and then on to Bayeux, with back to Paris as a last stop. My research says no, but thought I'd throw it out there.
Thanks in advance for any advice.
