From 22 May, SNCF in ticket offices or through SNCF Connect can no longer sell you tickets for *at least* these neighbouring railways (this list might not be complete)
NS 🇳🇱
SNCB 🇧🇪
SBB* 🇨🇭
Renfe 🇪🇸
Trenitalia 🇮🇹
DB** 🇩🇪
ÖBB 🇦🇹

* - except Lyria
** - except cross border FR-DE TGVs and ICEs
@quixoticgeek Not sure about Renfe or Trenitalia, but the others can. Also legs entirely within France.
