Observed (from a distance) the two Northern.Sky Charters cars on the head of #4 (30). I have no knowledge if the cars were revenue or deadhead or if there is any correlation with Mr. Backshop's observation reported immediately.
If the cars were on a revenue move, and absent an emergency, I'm sure the passengers "thoroughly enjoyed" the smoke, engines, and horns - and "have had words" with the operator and/or Amtrak. After all, when you are handling people who can reach into the wallet for something like that, odds get strong that "somebody knows someone".
