They were on the westbound Cardinal in this video posted yesterday. The poster didn't say what date it was filmed.I was on this train and I can confirm it was American View. We also had Pacific Bend and one more in between (Viewliner based) that I didn't catch the name/number on
It's not very clear, but the in-between car looks like a VLII sleeper.
Last week, the American View was on the southbound Silver Star, reportedly on the way to Miami having to do with the possible relocation from Hialeah to the new station at Miami International Airport.
