Reviving this old thread as I was recently wondering about the consistently dirty windows. Last time I took the Zephyr (two years ago) windows were washed manually in Denver. Are they still doing that? Does anyone have any new information on where Amtrak is washing windows these days, if at all? Where do they have automatic car washers outside of Chicago? Do they wash the cars before every outbound trip? Not that Amtrak markets long distance trains but having that great view out the window has always been a major selling point. We're all aware of the nickel and dining Amtrak has been doing for years to satisfy the overlords in Washington, but this would seem to me to be a valid expense.
