The scariest thing about Chinese high-speed trains is what if they drive one through my house?
It's so fast that they might send it across the ocean and I wouldn't know until it's too late. I've retreated upstairs so it can't directly hit me but it's going to collapse the support beams regardless.
if you're referring to the horizontal ones, you're correct. but if you're referring to the vertical ones, then it's "support columns". i'm sorry but i'd get an itch if i hadn't said that.
