Having read through the report two things strike me: The driver appeared to be totally oblviious to the danger he was putting himself and his passengers in, and Management look like they are going through the motions rather than actually managing. (I am talking here about the senior managers, not so much the managers on the ground, who look as if they are totally unsupported).
I work in a non rail safety critical industry, and what ever your training, or lack of it, if you dont understand something you ask, may be colleauges, maybe managers, maybe Google it, but igornance is not bliss. Looking at the drivers record it seems me to show someonre who is cavalier. The driver may have had medical problems or personal problems, but if he/she cant stay concentrated on the job during work hours then train driving is not the right career for that person. How many strikes do you need before someone says "Sorry but this isnt the job for you". I agree with trying to support people through difficult times, but safety has to come first, and redeployment may be the only solution.
Will any prosecutions result?
