Yup it's gonna be interesting seeing what caused the lead vehicle to derail. I wonder if there was a possession on?
I seem to remember a bit of a to-do outside Waterloo in an engineering worksite recently that ultimately led to a collision.
Oh yes, linky here......

It's that damn degraded working - glad we don't do that crazy engineering stuff in the wee small hours of the night - far too easy to mess up.
