The Governor of New York, Andrew Cuomo, has told CNN that the site where the North-West train derailed was "a dangerous area on the track just by design".
The trains are going about 70 miles per hour coming down the straight part of the track. They slow to about 30 miles per hour to make that sharp curve ... where the Hudson River meets the Harlem River and that is a difficult area of the track.
The US National Guard are distributing free food and water in New York today as part of a "million meal" aid initiative launched by Andrew Cuomo, the city's Governor.
Working with the Federal Emergency Management Agency (FEMA), the National Guards have been tasked with delivering one million meals and bottled water to people in the areas most affected by the disaster.
