She already told you what her source was, so please stop giving her a hard time unnecessarily.
The sequence of events as visible to me, as it unfolded (from my vantage point) was:
1. A message was posted on FB with the memo that I have since posted a pointer to in TO.
2. Soon after that it was removed saying that it is fake.
3. Trains Mag came out with their Newswire quoting from that memo, but not providing any pointer to it , somewhat naturally since it was an internal memo.
4. The Memo was posted in TO at a relatively innocuous place but an list that would be of much relevance - Steam Excursions
5. Borden Black (owner of "Dearing") posted a plea on FB Amtrak group explaining what they have been told and asking folks to start communication with Amtrak powers that be regarding the matter.
6. Most recently Seabord92 got verifying calls from friends in the know.
The current theory is that it applies to everything that Amtrak choose not to make an exceptional case of, which probably means pretty much everything in the current mood.
Although I suspect it probably does not cover the case where some party reserves a whole bunch of seats on a regular service and Amtrak chooses to add a car to accommodate them without killing space for normal customers.
