No - it’s socially strongly frowned upon to not mute your phone on a train, and it’s written everywhere that you should be quiet, so SNCF is just materializing this . I remember years ago group of four loud American tourists ( who were just having a loud conversation, they weren’t throwing beer bottles around )- passengers, not staff, repeatedly told them to be quiet. I still remember the look of misunderstanding of how of the tourists, who clearly didn’t understand what he was doing wrong.
