Faster Than A Speeding Bullet?

This is easily the fastest (And probably the coolest looking) train I have ever been on; the high speed bullet train from Beijing to Xi'an.

At it's fastest it was speeding along through the smoggy Chinese landscape at 304kmph! To put that in perspective, the Eurostar only just pushes past 250kmph and this train can even get close to 400kmph on the right tracks!
