I would rather compare the train/cruise ship to a packed theater/stadium, rather than a commandeered aircraft used as a kinetic weapon. You have potentially thousands of vulnerable people in an enclosed space with no realistic means of escape. The idea that a bombed train isn't going to be a major disaster is baffling to me. Train derailments invariably cause massive casualties to those on board. Heck, lock the doors and start a fire.
