A time-lapse video created over two days shows the track repair work underway at the site of a Metro-North train derailment where four people died and 63 people were injured.
Documentary filmmaker Daniel Cohen lives in The Bronx in a building next to the December 1 derailment site of a southbound Metro-North train. On December 3 and 4, he recorded this time-lapse of the track repair work. Cohen was home at the time of the derailment, and posted a number of photos of the site to his Twitter account, @danielcohen.
