What do you see when Marion clasps her hands in that fiercesome diamond shape? Click for a closer study. Takes a lot of hard work to build a tennis physique like this.

Rather dramatic SuperM; I like this post. That rail bridge also has the form of a train. Looking at a photo of the two Forth bridges, rail and road, the arching suspension bridge seems much less suitable for trains. Although, for example, the Tsing Ma suspension bridge in Hong Kong carries both road and rail. Then again, maybe those trains are not so heavy?
