Whilst the phrase 'trainee made an arse of it' may not be borne out in fact, the point surely is that a sequence of errors occurred and the equipment which should have broken that sequence failed to do its job. That is serious, and is what should be sorted, rather than pointing fingers.
We all know that most accidents are not caused by one single event, but a chain which links up. If any of the links are missing or are broken then the accident doesn't happen. If we are relying on the new equipment at Swanwick to break that chain and it is not doing so, then the travelling public should be alarmed!
