Hi HN, I'm Anton, founder of Luna Rail.

I've always thought night trains are a fantastic, sustainable alternative to short-haul flights, but they're often held back by a lack of privacy, comfort, and poor economics due to low passenger capacity.

I became overly fascinated with this puzzle. I view it as a kind of night train Tetris (my wife less charitably calls it "sardinology"). I spent way too much time learning about and sketching various layouts, trying to figure out how to fit the maximum number of private cabins into a standard railcar, while making them attractive for both day and night travel.

This eventually led to a physical workshop (in Berlin) and a hands-on rapid prototyping process. We've built a series of full-scale mockups, starting with wood and cardboard and progressing to high-fidelity versions with 3D-printed and CNC-milled parts, with various functional elements.

Hundreds of people have come in to test our various iterations, because you can't test ergonomics or comfort by looking at renderings (although we did create a bunch of nice ones).

The link goes to our home page showing our approach and some of the thinking behind them. It’s been a lot of fun working on this puzzle, and we're excited to share what we've come up with. We hope you think it's cool too and would love to hear your thoughts.

I love the concept and the renders, but I wonder... is the spatial optimization really what's holding train travel back? If you decrease passenger density in order to increase privacy and comfort, do you then have a corresponding increase in ticket prices?

In places with good train travel, it seems like they already have several cabin classes, from sardine seats (still luxurious compared to air travel) to private cabins (at several multipliers of price). Pod style rooms would presumably be cheaper than that, but still a lot more expensive than a seat?

Then in places without high speed passenger rail, like the US, this wouldn't really be able to address the major problems with train travel (slowness, lower priority than freight, low reliability, etc.).

Under what scenarios would using pods instead of cabins be more economically viable? And could these be retrofitted into existing sleeper cars, or would they have to build entirely new trains?

Clearly different markets have quite different requirements and comparisons to air travel.

For example a "night train" maxes out around 12 hours. A train from 6pm to 6am is functionally equivalent to a 8pm flight, arriving at midnight, checking into a hotel, getting some sleep etc.

How far you can go in that 12 hours (give or take) depends on the speed of the train etc. In Europe you can go to a lot of places in 12 hours. In the US not so much.

Much longer and other factors come into play. You have to balance the time cost of "getting there" to the time benefit of "being there".

But thats OK. This solution doesn't have to work everywhere. It can start where it works well and grows from there.

That is like comparing range in gas cars and EVs. Some do that but there are other major benefits.

The lengths I will go through to avoid air travel is much higher than a 1:1 ratio in comparable time. When I have to get the cattle treatment I prefer cattle cars over cattle cans.

And even with 1:1 remember that layovers are a completely different beast. If Münich was a hub between Northern an southern Europe I would be happy to spend a well rested day before continuing on. Especially in spargel season!

...but only a fool does not fear German railroads. They could really learn from the Austrians.

The reason night trains are not a thing is because there is no real network. Looking for tickets in Europe it is often once or twice a week departures on specific routes. No real good north south interconnected corridor from Scandinavia.

And as a proper geek I have even sought them out but often found them sold out.

They cost optimized themselves to obliteration.

The Snälltåget goes from Stockholm to Berlin almost daily and from Berlin you can take a daily Nightjet to Zurich. Not sure what you are missing.

Many things:

A) A hub further south than Berlin. If Dresden (end station for the line) was a "hub" then OK B) Hard to find and find intercomnnectimg routes. C) It departures from Copenhagen South not Copenhagen Central. D) Poor availability. You need to book in advance if you're not very flexible on dates. This compounds when you need to interconnected. E) Insane prices. They have optimized themselves out of business. CPH - Berlin in a private cabin for 2 will cost around USD $500. This much more expensive than plane tickets and a very nice hotel room.

If you talk with "regular" people this does not even register as an option. Hence a poor network is not comparable to a proper network. It needs to be able to compete - not on all parameters but at least some.
