Last evening, train-top travelling claimed another life, when a 25-year-old commuting on a Virar-bound local died instantly after being electrocuted by heavily charged overhead wires. Rooftop travelling became all the more dangerous since February after power supply to trains was augmented by nearly 17 times. As such, the current coursing through overhead cables increased from 1,500-volt direct current (DC) to 25,000-volt alternating current (AC). If a person even ventures within a 2-meter radius, there is a good chance he will be sucked in by the current, and the resulting electric shock may be fatal.
