Once established that the primary cause of the Santiago de Compostela train disaster which has claimed 80 lives and left around 100 injured in north-west Spain was an excess of velocity, focus is turning as how such a train could go into a corner with a speed limit of 80 km/h at a speed of around 190 km/h. A video of the accident shown on Spanish TV and posted on virtually every news website in the country shows in graphic detail how the carriages are hurled off the tracks as a result of the excessive speed, with the second wagon appearing to jump the tracks while those behind it are twisted into tortured shapes by the stress placed upon them.
