Shorter trains would also mean less severe derailments. Shorter trains also mean that trains are in risky areas for less time, less time decelerating and accelerating, so derailment could be far less than double. Shorter trains would also make coordination easier, because the current trains are too long for bypass tracks so currently none of these trains can pass each other and it tacks a very long time for a multi-mile train to clear the tracks. Allowing trains to actually overtake each other again would help with congestion, but that mostly helps Amtrack so companies don't care.
