The Netherlands Railway is one of the safest in Europe, I'm surprised this accident happened in the way mentioned in Stuving post
Having a good safety record means keeping the number of accidents very low, but no-one can get it down to zero. For this kind of work you need to be good at sticking to the procedures, as individuals and the whole organisation. But procedures are still operated by people, and unexpected things happen.
It looks as if the initial collision of the goods train with the
RRV▸ was in fact quite violent. Two pictures show this:
First, from a local railforums member (citycat) who came across
the goods train being recovered with its locomotive. It was taken from the undamaged (right) side, and at first it's not obvious how much of the far side ought to be visible but isn't. It's just not there any more (and that includes the buffer that side).
Then
this overhead view from NOS (roughly, a Dutch
BBC» news service). The two platforms used to end in line with each other, so much of the end 2 m of the platform the RRV was thrown against has gone.
