Hello all, We are used to riding trains overseas, and we're wondering how invasive the "Random passenger and carry-on baggage screening and inspection*" are? We no longer fly in the US because it's so unpleasant, and we're wondering if trains are a viable alternative, or we only have driving left for moving around the country. We are thinking of getting a sleeper car on a WPB->CYN->WPB trip later this year. I'm not sure if the security differs per station? I've read through a lot of postings here, but there's not much mention about whether we should expect radiation and groping, or merely metal detectors, questions, and dogs. Thanks for any advice!
