What movie am i thinking about please help

Soooo i cant think of the name of this movie. There is a part that goes like this. A man and his wife/girlfreind are on a prison train (Jews Maybe?) and they kill these two guys with a shard of metal. Then they start to pry these nails out of the floorboards through the bathroom hole in the floor. They drop the peice of metal. Then they use the dead guys tooth to get the rest of the nail out. Then they notice that at the back of the train are hooks on chains to prevent escape. They use the dead dudes bodies to shield themselves from the hooks and get away...


Please tell me what this movie is!!!

 

and its a pretty new movie or tv show i think... anyone???
