Was the Madrid event on a curve, or the straight away into a building?
The two times I entered the Madrid station, we were on a long curve - maybe 40-50 kph at the time. Certainy there were speed limits being enforced! The Spanish high-speed trains are almost as fast as the Japanese and French designs when going cross-country. On a station, when they go by, it is the same noise and air motion as if a jet-fighter flew by 10 feet away.
