The prop train used for the Money Train was an actual retired NYC subway train that was destined to be scrapped. After the film was completed, it was donated to the NYC Transit Authority and currently resides in the Coney Island Rapid Transit Yard.
The subway car used as the money train in the film is a modified R21 subway car. The car was modified by the Metropolitan Transit Authority and film crew in a way that looks absolutely nothing like the actual revenue collection trains used in the system. After production, the car was donated to the New York City Transit Museum. It currently is stored at the Coney Island Yard in Brooklyn as part of the museum car fleet and was briefly on display at the New York City Transit Museum.
Most of the subway scenes were filmed on a 4000-foot-long set built to resemble a typical four-track New York subway trunk line. It included three stations, all of which were built as local stops with the platforms on the outside of the outer tracks. Included were I-beams between each track, spaced five feet apart just as they are in New York. The ceiling, however, was much higher than on any actual New York subway line.
In the opening scene where Wesley Snipes hits one of the Money Train cops, there is a Die Hard 2 poster on the wall. Die Hard 2 was also written by 'Richardson, Doug'.
The Wall Street station scenes were filmed at the Union Square station on the IRT Lexington Ave. line. The 33rd Street station is the real one, on the same line. All scenes filmed on the subway set featured retired carbon steel R-30 subway cars, painted red. Scenes filmed on the actual New York subway featured stainless steel R-62 cars.
Robert Blake claims that his first meeting with producer 'Jon Peters' consisted of Peters wrestling Blake to the ground. At the premiere, Blake said Peters told him he wrestled with Blake to see if Blake would lose his temper.
Average & Median Shot Length = ~4.2 seconds.
While there are scenes that show R30 class subway trains running on the IRT Lexington Avenue Line, this would be physically impossible in reality. Due to NYC's subway having been constructed by competing companies, trains for the lettered lines would not fit on the numbered lines as they are too wide. IRT trains are narrower and shorter than BMT/IND trains.
R30 trains were retired from passenger service in 1993, these trains along with the IRT sized R33 and R36 trains were among the last in the system to never have air conditioning. The R30 would have become too heavy if air conditioning was added.
R30 trains were called BMT Redbirds for their identical paint scheme to that of the IRT trains.
Two days after the film opened, two men poured petrol over a ticket booth on the Brooklyn subway and set it alight in an incident similar to the one depicted in the film. The booth attendant was burned and later died of his injuries. Consequently New York subway workers called for a boycott of the film and the removal of all the posters from every station. Republican senator Bob Dole quickly came out in support of them. Columbia Pictures refused to bow to their demands.
This boasts the distinction of having one of the longest sets ever constructed for a film. At over 3000 feet long, 20 feet high and four railway tracks wide, the set was roughly the same size as two Empire State building lying side by side. The original plan was to film in the real New York subway but the logistics proved too problematic.
12 New York subway cars were shipped over to Los Angeles to the film set. They were converted to run on propane so that the rails on the film set did not need to be electrified - a potential health hazard for all the crew.
