European Sleeper Trains Make a Comeback By Adam Graham, 8/25/21, Wall St. Journal
While the CO2 savings from traveling by rail instead of air can vary, depending on the source of electricity each country uses, carbon-offset calculators such as EcoPassenger estimate that on average short-haul flights emit 77 times more CO2 per passenger than trains.
Not if you can use high-speed trains. While aircraft may fly between destinations quicker, for short haul flights the time spent at the airport makes the overall journey time longer. That is even without allowing for the journey times to and from the airports at either end.
And, in the case of sleepers you save a night in an hotel.
you are paying for as night in the train's "hotel" instead
If we had modern trains and good tracks though speed would be quite high. I did not know these had actually gone away. Brian
As is the journey time with a sleeper.
Trains may be more CO2 friendly if you are packed in with everyone seated but can you extrapolate that efficiency when you have to have extra rolling stock and give each individual person more space to sleep.
Good point, the number of people carried per ton of rolling stock is a lot less that regular trains.

You can if you are using nuclear power or wind power, where the CO2 emissions only come from the construction.
