Very sad. No details about the cause as yet. Many vehicles derailed, but they look largely intact suggesting a relatively modest speed.

It's noticeable that the leading vehicle has overturned on the outside of a curve.

True, though that tells us nothing about why it came off, only that it was on a curve at the time. Any derailment at speed on a curve, whatever the cause, is almost certain to produce that effect.

Now reported that excess speed was a factor in the derailment.

AIUI, there was a c40mph curve on a c90mph route. The local equivalent of ATC/TPWS had been switched out as faulty, without failing the train. There may not have been effective approach control signalling, as would apply in the UK.

Sometimes I think that NR/DfT/GWR etc are wonderful.....

...err.  where in the UK do we have approach control signalling for a curve in plain line?

I thought that we had it at Reading before the rebuild on the down main (125) into 4 (50). We were never slowed when it was 80.

Apologies if I'm mistaken.
