There was a recent thread referencing a race [Drag Race] between a real Locomotive and an electric model train. There was much speculation about speed and distance and who would win.
I think this link will shed a little light on that subject:

With a top speed of 168mph in regular service, and acceleration as previously mentioned-- This new Shinkasen is definitely one fast ‘get outa here’ train… Wonder how Amtrak’s Acela stacks up with this for acceleration?
