Since we do not know the facts of what caused the crash, it is premature to lay the blame exclusively on the driver. While that seems a likely cause, there are numerous ways that a breakdown in some part of the safety and warning system could lead to a crash. The engineer of the train is dependent on warning lights, signs, back-up safety systems. What if there was no kind of warning, due to a breakdown, that the speed limit was only fifty miles an hour? It could be that that particular section of track, if it had been properly maintained, would be safe even at 100 mph. At this point we do not know the facts. I doubt that we will ever really know the facts, and, despite whatever breakdowns due to lack of proper maintenance (i.e., lack of funding), the driver will end up taking the full blame from authorities.
Even assuming that the driver is 100% at fault, is it really a good idea to cut funding that goes to maintain and update safety systems for rail travel? The juxtaposition of the crash, whatever the cause, and Republican cluelessness is stark whatever caused the crash. It points out their utter disregard for the safety and well-being of the rest of us who cannot afford to travel by first-class air, helicopter, or chauffeured limousine.
