My apologies, when you referred to HSR, especially considering the context of Boeing, my brain deciphered that as “health & safety regulations”. I take it you are talking about a train system operator / railway network? And yes, train network in the US sucks compared to Europe, if I may say so as a European. But also here (Germany), it is painfully expensive - and I want to lynch some responsible politicians for making train tickets more expensive than regular flights for even short distances…
