1) There are people on this very forum who, just in the last couple of weeks (i.e. long after COVID became a factor) complained about toilets in rooms and wanted to know if they could book a trip and be guaranteed a new Viewliner without a toilet in the room. My memory on this is hazy, but as I recall when the new Viewliners were ordered, it was explained that those that liked an in-room toilet and those that didn’t were somewhat evenly split, but those that didn’t like it felt much more strongly against it than those who liked it felt strongly for it. This was among all passengers, not just AUers/railfans.
2) COVID won’t always be a factor, and railcars have a 40+ year service life. Toilets in every room was easy when railcars didn’t need plumbing. Now that they do, it requires a lot more maintenance. That adds to cost x 40 years.
3) If COVID bothers you a lot (and I’m not saying it shouldn’t, it’s a serious virus with potentially deadly effects), the answer is really to stay home, not to worry about the 2-3 minutes at a time you’ll spend in a restroom shared by a few others).
4) Amtrak management absolutely do know what it’s like in roomettes
5) If you think roomettes are too small for two people, feel free to book one just for yourself and not share it with anyone. Nobody is stopping you.
6) A [Democratic] administration has nothing to do with anything regarding roomette design. The Viewliner IIs were ordered under a Democratic administration (again, not that it means anything). All of the current Amtrak board members except for Elaine Chao (as Secretary of Transportation) and William Flynn (as CEO) have been around since the Obama administration. It still takes both houses of Congress to pass a bill that would legislatively direct Amtrak to do anything. So, what’s supposed to change?
