Ok so to clarify. The 66/67 used to run with a combination of diesel and electric locomotives. (presumably to save time when swapping power in WAS?) Now they are running only electric (I assume North of WAS and there is the normal swap to Diesel South of WAS?)
Then the next obvious question. There was a viewliner on the consist. It was between the baggage car and the locomotive so not in revenue service and likely removed with the engine in WAS?
IIRC others have advised 66/67 used to be called the "night owl" and ran with sleepers at one point in history
Just making sure I have it right. Again understand a little bit of a neophite here. Ask me about commercial aviation and I can cite facts and statistics rote. Trains are a new variant for me.
I am not sure if it has been called the Night Owl but it has definatley been called the Twilight Shoreliner and reaching into preAmtrak history has been called the Federal.
Yes, definatley there have been sleeping cars in its past, the further back you go, the more cars.
Under the preAmtrak name Federal the most noteworthy thing it ever did was lose control and slam into Washington Union Station. The station was full of people in town for President Eisenhower's inauguration in the early 50s.
Various trains around the country have been called names like Owl and Night Owl through the years, esp. preAmtrak.
