No REASON TO BE, unless you plan on touching it. Hundreds of volts, but they don’t jump out at you. You have to go looking for them, to get in trouble.Easy enough to step over, even in lousy shoes. I figured whatever my rubber footwear would subtract in terms of precision control, it would add in terms of electrical insulation. But even so, I planned my moves very carefully, like stage choreography. Jump down, land two-footed in the centre of the uptown line, right foot on the second rail, left foot beyond the third rail, squeeze through the gap between two pillars, right foot over the next third rail, left foot on the downtown track, small careful mincing steps, then a sigh of relief and a scramble up on to the downtown platform and away.Easy enough to do.Easy enough for the cops to do right behind me.They had probably done it before.I hadn’t.I waited. Checked behind me, left and right. The cops were close. Close enough to be slowing down and forming up and deciding exactly how they were going to do what would need to be done next.
