 CONT: At the beginning of the movie, when the Russian Officer  secures the rail car that contains the nukes, he opens a panel on  the rear of the car which features two columns of buttons with  numbers, and a red button at the bottom left, and green button at  bottom right. Later during the hijacking, he opens the same panel to  open the car door, yet the red and green buttons are at the top of  the columns now.
