A Spanish train that hurtled off the rails and smashed into a security wall as it rounded a bend was going so fast that carriages tumbled off the tracks like dominos, killing 80 people, according to eyewitness accounts and video footage obtained Thursday.
An Associated Press analysis of video images suggests that the train may have been traveling at twice the speed limit for that stretch of track.
Eyewitness accounts backed by security-camera footage of the moment of disaster suggested that the eight-carriage train was going too fast as it tried to turn left underneath a road bridge. The train company Renfe said 218 passengers and five crew members were on board. Spanish officials said the speed limit on that section of track is 80 kilometers (50 miles) per hour.
An Associated Press estimate of the train's speed at the moment of impact using the time stamp of the video and the estimated distance between two pylons gives a range of 144-192 kph (89-119 mph). Another estimate calculated on the basis of the typical distance between railroad ties gives a range of 156-182 kph (96-112 mph).
