I grew up in a surburban town with a train line through it that was electrified via a third rail. So two sets of tracks, in each direction, and two third rails in the middle, for each direction.
All sorts of bollox was talked when we were kids about how the rail could kill you. Like if you just touched it with your foot you’d be dead. No, you could stand on it and you’d be fine as long as you weren’t touching the ground. No, that’s not right, you need to touch both electric rails etc etc.
What’s the SD here? Would simply placing your foot on the third rail lead to electrocution?
