Thalys train attack? It was an AKM, not an AR. A simple metal detector would've caught a long gun, even with incompetent security personnel. By only allowing small "carry on" bags in the passenger carriages (storing larger "checked" bags in a separate freight car) the attack space is limited to what can fit in a handbag or backpack. It won't catch everything, but wrt terrorist attacks trains are safer than airplanes. You don't need to go full TSA and make grandma take off her shoes or racially profile people to have decent security.
