Thank you, Peter.  

Surely the lesson of the Morpeth derailments is that speed limits on tight curves need to be enforced technologically, not merely procedurally by the imposition of speed limits.  

According to Prof. Roger Kemp of Lancaster University, quoted by MSN, the accident in Spain occurred on a section of ‘half completed’ track that was still being brought up to date with the safety standards of the European Rail Traffic Management System, which would have prevented the train from exceeding the speed on the section of track. e-uk569032  

If this is true, the driver should not be the only one under investigation.

I have just one comment - "Morpeth" 1969, 1984, 1994!

Hear, hear!

If some technological failure caused the accident, we need to know.

If some technology misled, confused or distracted the driver at a critical moment, we need to know.

If some technology that should have intervened was absent, switched off, or otherwise ineffective, we need to know.

The (seemingly) media-led frenzy to find someone to blame is an obstacle to the prevention of future accidents. Even if the technology is not at fault, we should still be asking what would lead an experienced, well-qualified driver to act (or not act) in the way he did. Then we have a chance of improving things. We won't if the 'blame game' takes priority.
