I agree about the noisy people. I will observe, it has not been a problem for me on Western LD trains, only on the LSL in the East. On that train, in coach, I have been kept awake a few times, and I have complained with mixed results. I have found that getting up and moving, if there is a vacant seat somewhere else, is sometimes the best option.
Back to the article... I too went back and read the comments on the Times website. It seems that the majority of them are from people remembering how much they enjoyed the train ride two or three decades ago. A lot of them are people complaining about subsidies, some with responses from other commenters reminding them that roads and airlines get hefty subsidies, albeit less visible, as well.
To the poster here that said they doubt there will be another article for 5 years... maybe you don't read that paper that often, but I can think of at least two articles in the Times this past year about Amtrak travel: One about the quiet car in the Northeast Corridor, another feature about the Zephyr with some nice photos.
Let's face it, we Amtrak riders are a very small minority. One of the commenters in the Times quoted a car attendant that told them (I paraphrase here) "For every 10 people who ride for the first time, 9 of them will never ride again, and the other one will never travel again any other way!"
Best to you all.
