Nice! Wish we had those here in the states.
Our Amtrack trains had their speed limits raised to 80MPH or 85MPH a couple years ago. I chased one along the Columbia river, east of the Gorge for a couple hours one day. Took me almost an hour to catch it and pass it, doing triple digits, but I couldn't stay with it. They get to go in a straight line, while I had to follow the winding / twisty highway. Still, it was a very fun couple of hours, and helped me get home after a 3 day riding weekend a little quicker.
Don't think you could pace that one for long, at least not without a few flashing lights behind you.
