And I don’t read it that way. That’s why it’s ambiguous.

I am even more confused with that link, though, because they do seem to have listed lines in Spain flagged as “important seat-only connections”. So… connections to where? Why are they cut off? Do those extend into Portugal or terminate in Spain?

… yes, I know what a night train is. Your point?

For the record, there are far longer routes in Ireland, Spain and Portugal and far shorter routes captured in the map (in distance, we could have a long talk about the pros and cons of promoting overnight train over high speed rail for the same trip).
