So the pieces were made to fit based on where the train stopped. The lift pieces are different from the brake pieces per say. From the pictures I have seen, it didn't look like anyone other than park staff was working on the evac, so maybe they just wanted them there as backup? Maybe someone was having a medical emergency during the evac? Again, we don't know for sure and probably won't know the exact reason why. For all we know, a new operator freaked out, called the park emergency line, and told them that they need rescue, so dispatch called. I haven't done anything that bad, but I have made some pretty stupid calls to dispatch.
