I was reading up New York City Subway accidents and I came across this photo from August 1991 showing a derailed No. 4 train just north of Union Square. Apparently, the motorman was drunk at the time and going way over the speed limit in that particular tunnel. He was later convicted of manslaughter and sentenced to 15 years in jail (5 people died in the accident).
