"Most of the 264 passengers and 30 crew members debarked there Saturday morning, most of them in good spirits despite the ordeal."
I wonder if there is a very informal verb/phrasal verb that could replace this one, please.
Although I could recognise what it meant, I have never personally used the word "debark", and so checked it out in the various on-line dictionaries.
All suggest that it relates to ships or aircraft.
The word that I would have used would be "disembark", if I hadn't known that it was from a train - the suffix "-bark" comes from the French word "barque", which means a ship.
The informal way, as Banderas says, would be: "got off the train", in your case.
