Real pity. It was an important idea that should have gotten a chance.
Check out European sleeper, that company is already doing this
and NightJet by ÖBB, different routes, but a lot better IMO
As far as I know those services are barely breaking even, using the few remaining old sleeper wagons. Growth of them is not likely because new wagons cost a lot and profitability is low.
Just put less rows of seats and have them properly recline. Some people will want small rooms, but cheap sleeper seats help as well. People sleep in planes too.
I want to say that sleep is terrible because blood flow isn’t as good as when lying down.
There is a reason pressure socks are sometimes recommended on very long flights even for people with no prior heart issues :)
Why? Sounds like a small expensive hotel and a slow plane ride.
Or a better night train. The slowness is not an issue if you can actually save time by merging the trip and the hotel stay.
There’s already a company doing this, with lines already going. European sleeper! Night trains with private cabins and beds between Brussels, Amsterdam, Berlin and Prague
Right, Midnight Trains was a French company trying to create a European night train network that centred on France, specifically on Paris. I think they found out the hard way that for various reasons, as they detailed in their blog, France might not be the best country in which to organise such a company; it also might have been simply too ambitious of a project for the current market.
Ah, that was on my list of “looking forward to try”. The Porto to Hamburg line they had in their promotional material sounded really cool.
