  • Derailment in Neufville, Belgium

    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]

    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.
