John Travolta chose not to promote the film with the rest of the cast because he was still reeling from the loss of his son Jett.

The New York Transit Authority for years after the novel and the original film barred its planners from scheduling a train leaving Pelham at 1:23 in the morning or afternoon. Although the policy was rescinded, as a superstition the dispatchers still avoid scheduling a train at that time.

The movie pays homage to Walter Matthau, who played Lieutenant Zachary Garber in the 1974 movie by naming 'Denzel Washington's character Walter Garber. Also, while Lieutenant Zachary Garber wore a plaid shirt and yellow tie, Walter Garber wears a yellow shirt and similar pattern plaid tie.

James Gandolfini's portrayal of the Mayor is an obvious composite of two real former NYC mayors: his appearance and attitude is clearly based on Giuliani. However, an exchange between him and Ryder, where Ryder teases him about taking an annual salary of only $1, is a clear reference to Bloomberg.

Ryder says to Garber, "You live, you die, you either go with the current or you fight it, but you all end up in the same place", to which Garber asks, "Where's that, Jersey". Ryder then says, "Yeah, you watch it, I was born there man." John Travolta, who plays Ryder, was born in Englewood, New Jersey.

The title derives from the train's radio call sign. When a New York City subway train leaves to make a run, it's given a call sign based on the time it left and where, in this case Pelham Bay Park Station at 1:23pm.

Garber talks about choosing between purchasing trains from a Japanese company and a Canadian company. Although not mentioned by name, this refers to Kawasaki Heavy Industries and Bombardier Transportation, who have both manufactured subway trains for New York.

The R-142 and R-142A subway cars portrayed in this film are permanently linked into 5-car sets and cannot operate as single units.

The original movie was released in 1974 and the remake in 2009, 35 years later. Robert Shaw starred in the 1974 version and James Gandolfini in the 2009 version. Both men died of heart attacks 35 years apart (Shaw in 1978 and Gandolfini in 2013) both men were aged 51.

While negotiating with Garber on the phone, Ryder says the hostages aren't getting pizza. In the movie Inside Man, Denzels Washington's character is a hostage negotiator who sends in pizza for the hostages being held in the bank.

In the novel, the ransom demand is $1 million, and so it was in the original film, but the remake has upgraded it to $10 million. Ryder says a million dollar ransom is a corny asking price.

An officer gives Garber a stainless Walther PPK and puts it in one of the money bags marked with a wire tie on the handles. But later when they get off the train. As one of the bad guys is carrying one of the bags, a gust of wind from a moving train causes a bag to fall on the ground. Garber reaches down and pulls the gun from the bag to put in his pocket. Now the gun is something completely different from the Walther PPK that was originally given to him by the officer .

The seemingly bad continuity random shots including rain, over parts of the city, may be actually written off within the story, and reality, as a legitimate weather pattern where rain clouds might just happen to pass over localized areas while raining, leaving the rest of a large area dry. This isn't such an unusual weather event, particularly noticeable in cities.

In the novel, Ryder's mother died of cancer, and his father was bludgeoned by an ashtray. He entered military service, like Vietnam, and perhaps this was the case in the original film, but doubtful in the remake.

In the remake, his marriage is in trouble but not for the same reason. The Mayor (Sam in the novel) even considers letting the hijackers keep the train because New York doesn't have a million dollars, which was a lot of money in 1973 when the book was written.

The hijackers use tommy-guns in the novel but not the remake, perhaps because they're only effective at close range.
