4) Finally, I would note the specific issue described here seems to be that the teens may have seen one train coming and in an effort to avoid it they stepped from the track they knew was active, to one w/an oncoming UPX vehicle they did not see coming. This is a common feature in train/trespasser collisions that are not suicides. Here again is there a sensible instruction to give? In a two-track scenario, the obvious thing to say is always step to the side of the active track, not to the opposing track (assuming that's feasible). But if you're walking down the middle of 3 tracks or 4 tracks etc. Other than.....don't do that, I can't think of clear advice on the lowest risk option if you see a train coming, do you step to the left or the right?
In theory, properly positioned, you probably have room to stand between 2 moving trains, but not much (approximately 2.5ft, assuming neither train has a wide load, and there is no shaking/shifting at all) , and I would not recommend anyone try.
