That will delay the opening considerably I suspect. At least it wasn't a regular train full of passengers...

The French railways have safety systems that prevent overspeeding but as this concerned a test train on infrastructure that has not yet been commissioned, I have the suspicion that these systems were disabled or not functioning yet.

After checking the reports and the area it is apparent that the TGV derailed at the junction of Vendenheim, the eastern end of the LGV Est. This means the train must have failed to break ahead of the curve to exit the LGV and join the main line. This also means that the safety system (TVM or ETCS as both are used) must have been either not in use or failing.

It being a test train I'm fairly sure that those systems would have been disabled. One of the points of testing, after all, is finding out how fast you can go.

...I'm kind of surprised there was that many people on the test train.

In fact it seems that the train has been overspeeding right at the end of the high speed track (LGV), when the train line goes to the old line...

About the people, they where that much because the people that worked on it brought some of their families with them... it's even sader...

Given the speed at which the train was travelling, and seeing how far the cars actually rolled away from the track (note the swathes of torn-up grass), I'm actually very, very surprised that there were any survivors.

Is a train, not a plane.
The design of the train worked to protect passengers.

Oh, by the way... much better than the Transrapid when crashed at only 162 km/h...

Don't think so since the Transrapid didn't derail also this accident shows that Jacobs boogies doesn't have any effect at high speed.

this is the Location in OSM
looking at the skidmarks in the picture above they must have come from the west and then the train pretty much flew across the canal.
What i find strange is that the derail must have happened where the curve begins which means crazy overspeening or something on the tracks..

aw man were they trying to show off and then forgot where the old line begins?

this reminds me of the train wreck in spain a while back, was similar situation, just that there was a wall instead of a canal

So sad. My thoughts are with our French friends.

We now have two consecutive high-speed train derailing accidents due to overspeed, as the disaster in Spain with Renfe two years ago had a similar cause. Very distressing.

Cause? Yes. But the circumstances here are very different. This wasn't a passenger service, it was a test train which means the safety systems were probably turned off.

On a finished line with safety systems fully working this couldn't have happened.

In Spain no safety systems were even in place to prevent speeding. That was a huge oversight, considering the steep decline in allowed speed on that railway.

Circumstances are always different, so we have to wait for the final forensic results. Whether it’s a commercial service or a test run does not matter. People have lost their lives.

I am hopeful that the overspeed was not a result of a driver error, as a driver error could have been prevented. Especially after the recent Spanish accident.

Not necessary, if it was a test.
As it was explained in a previous posts, safety systems were probably turned off.

Some kind of safety procedures still must be observed during such tests. It's not the first time SNCF organises such tests...

By the way which system would normally guarantee that a train doesn't overspeed in spots where LGV turns into a regular line? That Spanish line had nothing at all except a diligence of the driver?

I, on the other hand, really hope that all the safety systems were turned off and it was a driver error. The allowed risk for tests is probably magnitudes higher than the allowed chance of an accident on a passenger service.

If it turns out that the systems were enabled and it was a system error, it would set back opening the line for possibly a very long time and be a concern for other high speed rail lines as well.

This is true, but I'd like to point out that if you are on a test train you do have to accept a somewhat elevated risk to yourself than if it were just a commercial run. It is just part of the nature of testing situations.

You forgot about the NEC accident earlier this year (also an overspeed).

The only real consolation here is that this happened on a testing run...

At this rate Japan is the next country to have the Major Deadly High-Speed Train Crash bug bite. Geez.
