The Taking of Pelham One Two Three

In New York City, four men wearing similar disguises and carrying concealed weapons board the same downtown 6 (New York City Subway service) train, Pelham 1-2-3, at different stations. Using the code names Mr. Blue, Mr. Green, Mr. Grey and Mr. Brown, they take 18 people, including the conductor and an Undercover operation police officer, hostage in the first car. They uncouple the car from the train and park it down the tunnel below 28th Street (IRT Lexington Avenue Line).
