I really appreciate the raised platforms that China builds for its rail tracks. They're used extensively in urban and rural areas, allowing wildlife, people, and vehicle traffic to cross, thereby making it safer for all parties involved (especially rail passengers).
OTOH I've never seen a raised rail platform in the US that wasn't part of a necessitated bridge. So many accidents like the one I posted this morning could easily be made impossible with a little bit of up-front spending.
That's it! 
That's the Grand Narrative of History that brings everything into focus! 
Comrade, you're brilliant!
