Hi Pantload,
if the SOP were followed, an unfavorable outcome would have resulted?
There will be many examples where the unintelligent application of the SOP will result in unfavourable outcomes. e.g. the coal train with a brake fire:
The fire was noticed by the "alert" crew who performed the SOP "Stop the Train".
Unfortunately, the train was brought to a halt with the burning truck in the middle of a wooden bridge. The bridge caught fire and eventually collapsed taking the rest of the coal train with it. The picture I have shows the very last truck just on the edge of the bridge.
The more intelligent application of the SOP would have been to stop the train about 100 yards further down the track.
