How are the cleanup efforts going right now . Well, stephanie, i would say crews are on the final stretches of work, at least here on the scene they brought on a out a cadaver dog. They uprighted most of the cars at this point. This is the final car. If you can see through the bushes here youll see that final car there. They were just able to upright with these large cranes that theyve been using and theyve been hauling the other cars away. In fact the one youve been looking at, the earlier video, this is the car that was just inches from the water, where near where the hudson and harl rivers meet. That fourth person found inside the car. They were able to upright the cars. There were seven of them total and 150 people aboard as weve been reporting when this train was en route to Grand Central station. Crews have finished their work
