It looks like the couplings, brake hoses and safety chains etc were all disconnected and stowed, so possibly done deliberately? Did they just forgot to disconnect the gangway cover between the doors on the two carriages? Or did they manage to ignore all those disconnected and stowed brake system hoses before taking off with disconnected coupling? Surely there would be an SOP to check such before moving out? If not, I'd bet there will be now.
And is that the Fat Controller stepping into the foreground about three-quarters of the way through? I'm sure he had something suitably stern to say.
