SNCF: how can a “non-striking controller” single-handedly save the departure of 500 French people on vacation? TGVs, but also Ouigo, Intercités and most TER trains cannot operate in the absence of a controller on board.

SNCF CEO Jean-Pierre Farandou tried to reason with the controllers, while a large part of them are preparing to walk out.
