As an occasional keen user of the old Sleeper, I had been looking forward to trying the new one.
However, with a poorer, noisier ride, and all the ongoing issues, at a much higher cost, I will not be risking the erratic (in several ways) experience.
Very disappointing, but I’ll just take a daytime train, probably on the previous day, and stay overnight, when I need to be at the destination early the next morning.
I hope more thought and care goes into the design and operation of the planned new European sleepers.
