It's also easier to stop a train, get off a train, or prevent collateral damage in case of malice/accident. Survivors are also a lot more likely if there is an accident, mostly because of gravity.

Very true. Even in the worst train derailments you never hear that there were no survivors.

Assuming passenger trains of course. I think a freight hijacking is far more likely. The danger posed by a hijacked freight are evident from the huge numbers of lives lost from exploding petroleum trains over the past few decades.
