I checked the video and found that this is recorded at Munich central station: at 1:01 the ad behind the train says ''Bahnland Bayern''(Baravia, the state of railway), and this station is obviously very big, then I'm almost sure that this is Munich central station, but 1:22 gives me more evidence: there is a pwc building at the direction of the train, and if you search pwc near the Munich central station in google map(simply move the map to Munich) you can find exactly the same building as in the video……
Oh how I wish I'd saved the clip of two Virgin Azumas (I'm pretty sure they were) performing likewise and set to the soundtrack of the Spice Girls' 'when two become one'!
