yes, because what if one of those people is touching the power rail? What do we know about the demographics of the people walking? How do we know they all made it out, or is someone lying down somewhere on the track?

There's no power rail. It's overhead power - that was the problem. According to the union a manager providing strike cover was responsible for damaging the overhead lines - https://www.standard.co.uk/news/transport/gwr-train-cables-p...
