Out of curiosity, are the US crashworthiness standards that much more onerous than those in Europe? I often see those standards cited as one of the reasons why Amtrak cannot buy train sets that are closer to their off the shelf European counterparts.
One would think that, given Europe‘s extensive history with HDR, they would have developed sensible crashworthiness standards. It certainly appears to the casual observer that their standards have, by and large, kept European passengers safe for decades. Does anyone have a view on whether our more stringent standards provide meaningful incremental safety benefits? Or is it more of a not invented here thing?
