Black Monday

It was a black Monday for nearly a quarter of India’s population as the worst power crisis in almost 10 years led to the northern grid, the largest arterial network for power in the country, collapsing early in the morning. 
The crisis began when an interconnecting substation in Agra tripped at 2.35am. Within seconds, all stations in the region connected to the grid shut down, plunging Delhi, eight other states and Chandigarh into darkness. 
The aftermath of the outage crippled normal life. Some 300 trains, including Shatabdis, Rajdhanis and Durontos, either came to a halt, leaving thousands stranded, or had to be cancelled. The Delhi Metro was all but grounded for over an hour. The service was restored in phases, with total normalcy returning only by noon.
