Mainichi has a pic of the accident online, wow, this scene does not match the engineers story at all. How could a 72kph/45mph wind "float" cars that far off the tracks? How fast was the train moving when it derailed? Damn, it's a miracle that innocent bystanders didn't get killed when the rail car hit the building.
Edit: now Mainichi has a photo special up with about 30 pics.
