But I do have a genuine concern for safety - as Counsel who prosecutes for
the
Health and Safety Executive on occasion. Working in a dark tunnel, with
two
electrified rails fills me with horror!

You'd have a heart attack at some of the sights I've seen in my time then!

Seriously though, as long as you're careful and watch what you're doing,
there's nothing wrong with being trackside with the juice on. If traction
current was turned off every time someone had to go trackside there'd be far
more delays!
