Yes, the NTSB requires any passenger rail car that is on a train network that is somehow connected to rail that carries freight to be built to standards for collisions with freight traffic. This is ridiculous, because it means we can't import those high speed trainsets, even in the northeast corridor, where the tracks are Amtrak-owned, and do not see freight traffic, just because the rails do link to the freight network.
