The subway car used as the money train in the film is a modified R21 subway car. The rolling stock was modified by the Metropolitan Transportation Authority and film crew into an imposing subway train covered in silver armor plating and equipped with flashing orange lights and sliding barred doors, like those on a jail cell. After production, the car was donated to the New York Transit Museum, and is currently stored at the Coney Island Complex as of February 2010. Other cars were used as props in the movie.
