I’m not well enough informed to clarify that issue. That whole freight train only had two men on board at the time of the accident. Both died.
I’m not sure of the crew on the Metrolink. Perhaps someone can explain that to us. I wouldn’t be surprised if there was only one Conductor on board, but there may have been several.
Whether one rides in the cab or not, I wouldn’t know either.
BTW, the conductor on the freight train was not in the cab with the engineer. I believe he was a few cars back.
All diesel-electric locomotives require an operator with constant pressure on the "deadman" (great choice of words, huh?) pedal.
I have not seen more than one working conductor when I rode the train. I have seen more than one on a train going back to a certain station.
