No, the article is trying to construct the narrative that people haven't heard about the train derailment. That claim is in the article's headline. That claim is in article's the first paragraph. And that claim is false.
The truth is it's received domestic media coverage and it's even received international media coverage. It's pointless to claim otherwise.
If you see a news title reading "This happened there and you haven't heard about it" but you have actually heard about it, just move on.
What's the point of saying "I have actually heard about it?".
