This has always been a thorn in my side too. I have no compassion for those who constantly make excuses for trains that are tattered, beat up, torn seats, strewn trash bags everywhere, dirty corners in the bathrooms and other cars. And yes those really disappointing windows.
Actually, I've never seen any of the problem that you've described, or should I say "imagined."
The amazing thing is that I've never seen an Amfleet seat with a torn cover and that 30 year old cars are remarkable clean and show very little wear for their age.
As far as dirty windows, I'd challenge anyone to compare their own car's side windows to those of an Amtrak coach. In the middle of the winter, is your car dirty on the outside? Actually, I'd wager that the inside of an Amtrak coach is far cleaner and tidier than the interior of 99.9% of the personal automobiles on the highway.
Your comment hardly needs comments as its as far out as any I have seen. Even the most ardent amtrak supporter here will normally conclude that there are a lot of issues onboard and outside on may trains.
However since you insist.. Too bad I didn't take photos.
Last business class trip to chicago on the Saluki which was last year, the backs of many of the seats were ripped or torn exposing the insides of the cushion. The window curtains were hanging with half the connectors missing.
My first lakeshore trip back in the 80s had torn seats though out the dinner with cushions falling off the front of the benches. Trash bags dumped everywhere. On our last lakeshore trip the roomette I had the curtains to block the view in to the room neither lined up in a way which would allow for decent privacy. The light on the wall wouldn't work and the bulb fell out in my hand when I tired to turn in on. Oh yes, the first lakeshore trip on boarding the sleeper my room had muddy foot prints on top of the seat. My moms bedroom had rigged latches and everything rattle so loud you couldn't hear above it when the train was riding roughly. The bathroom door banged shut constantly due to a faulty latch keeping her awake. The diner had a table in the center of one section removed and it had boxes stacked three high instead. A lovely professional site for sure. Water dripped in the though the covers between the sleepers making the floor dangerously slippery.
The toilets on the CZ refused to work from Denver to California. The rooms had duct tape on all the cabinets and doors trying to keep them from banging.
Not to mention the numerous times the cars were either so hot or so cold as to be nearly unbearable, seemingly unrelated to outside temperatures.
Many cars have obvious crud along the walls of the rest rooms and up the walls.
The windows on the CZ both trips I took it out of Chicago had cloudy windows which detracted big time from the view. The dome on the Capitol Limited was so dirty you couldn't see though the front of it.
I could probably go on for pages as I am sure others could..
But as I said when I worked that you have to be able to see dirt in order to clean it and some just don't see it.
