Perhaps it was posted here because it seems to have a remarkably broad scope going well beyond what might be considered railway-related? Just guessing, not the OP.

I am curious though, what part of the title indicated to you that there was something humorous in it?

This was the pattern I read in the title: "[Country] [Government org] Works Manual".

Surely, I thought to myself, the only reason this would have made it to the HN front page is if there were a few guffaws in it related to how asinine a government document could be, but I couldn't find anything in there that indicated the same.
