From about 380 kph, vibrations in the train became more and more noticeable.
At 490 kph passengers became slightly dizzy.
At 540 kph it became difficult to remain standing despite the stability of the train.
At 570 kph, the driver - filmed on camera - wore a very big smile.
"We had no worries - no birds, good weather, none of the troubles we had during the tests," said driver Eric Pieczak.
