Looking at that photostrip, I have a sense that there were some lucky elements in that crash. The train stayed upright, and the damage from the lorry didn't penetrate deep into the passengers saloon. That's not to say it wasn't truly frightening for those involved, merely that if one compares to the Great Heck or Ufton Nervet, it was thankfully less severe.

It does look as though in the steel verus aluminium battle the steel (from the truck presumably) won!

As mentioned above, I fair degree on luck involved there.
