I'm not seeing the link either.
It asks for a login.
One question I would like to ask about trains that may be covered in the article, is why that modern trains got rid of streamlining.
Sure passenger trains are still streamlined, but what about average freight trains ?
They go so far as to have exposed ladders on the sides, and look like a blunt anvil.
I have seen others explain it away as " Well they don't go very fast ", but as we all know, even at 45 mph there is a huge amount of drag.
