We will be traveling to France in April 2022 and taking a train to Normandy, Chartres, and Rouen from the St Lazare train station in Paris throughout the week. When I look at Google Maps, it looks like I should get tickets for the TER train versus the TGV. Can you buy a pass online to ride the TER regional trains or would it be better to buy them at the station? Thanks!
I recently rode a bunch of TER trains. I downloaded the Oui SNCF app and bought the tickets through that.
I bet that 61 guy would have some thoughts.
Or, when you're near any train station (and there are a lot), pop in and buy them at the ticket machines.
Phred's cryptic reference is to The Man in Seat 61, essential to any train travel. However, municipal systems are not his specialty. See:
