The only death rate on trains I care about is deaths from the train crashing/malfunctions/etc. You know.. Things the train/train operator are actually, legitimately responsible for.
People being fucking stupid and going around barriers and getting hit and killed should not be held against trains.
Trains are not hiding in a bush waiting to jump out and get you when you least expect it. They are enormous fucking things, stuck to rails, and the only way they are gonna get you is if you are a momentously self centered idiot (you know, you're average american) that tries to put yourself in a place where common sense and barriers tell you not to.
Then again, it doesnt matter to anti-mass transit propagandists who love to seize upon any opportunity to say "THIS IS TOO DANGEROUS/EXPENSIVE/UNAMERICAN, WE NEED MORE ROADS AND CARS INSTEAD"
