I went to maps.google.com and I measured the route and estimated the radius of curvature at the derailment spot. It was about 400 m (130 ft).
I then found the centrifugal acceleration. For 80 km/h, it was 1/8 g, while for 190 km/h, it was 0.7 g.
For flat track, the maximum safe height above the rail of the center of mass goes down from about 6 m to about 1 m:
Standard gauge: 5.7 m to 1.0 m
Iberian gauge: 6.6 m to 1.2 m
For track tilted for 1/8 g centrifugal acceleration, the maximum safe height goes up to 1.4 to 1.6 m for the two gauges.
