They used to need at least four…a thru sleeper from Washington to Boston, plus the “set out/in” Washington to New York, each way.This is one of those, “I can’t understand why this isn’t already the case” situations.
I rode the sleeper on the new night owl several times - it’s an extremely useful service. Every time I was on it, except for the inaugural in 2021, it was almost full. It’s one of the few areas where a sleeper train makes complete sense.
Are the two V1/2 sleepers simply not available?
There was never a Boston to New York sleeper, at least not since the New Haven RR era…
