Derailment in Neufville, Belgium

[Robert]

Two empty Desiros were involved and one coach ended up in a field. The
driver was taken to hospital for a check-up.

What is concerning to me - looking at this image - is the passenger
saloon being open to the outside world after the gangway is ripped off.
I believe these gangways are designed to be separate components to the
actual vehicle, whereas on older stock they would be equally-attached to
each coach (sometimes with an intermediate door).

I wonder if a redesign is in order?

[copied to uk.r as UK has these type of gangways as well]

Cheers,

If you look at photographs of pretty much any crash you will see the same
thing. Fundamentally the coupler is designed to bear the load of the forces
between carriages and hold them together (or apart), not the gangway
itself. If the train derails and the coupling can’t keep the carriages
together in their proper alignment, no design of gangway is going to
survive. Images of Hatfield, Greyrigg and Ladbroke Grove, for example, all
show examples of parted gay ways with exposed carriage interiors.
