TGV Est trial: experts blame the test manager and the SNCF. The causes of the accident are known: excessive speed and braking too late.

Concerning speed, the experts particularly regretted Systra's request to carry out overspeed tests 10% above the design speed of the line. “The issue of high-speed braking was not under control and no one took into account the problems observed,” they summarized. The hearing of these experts is due to continue on Monday.
