The 15:17 to Paris

The first person to tackle the terrorist on the train was a Frenchman. He later turned down the Légion d'honneur and asked to remain anonymous because he feared reprisals from other Islamists living in France.

A character during the Colosseum scene mentions that in ancient Rome, "thumbs down" meant to kill your opponent in a gladiatorial match. In actuality, "thumbs up" meant to kill your opponent, while "thumbs down" meant do not kill your opponent (literally, put your weapon in the ground). However, most people make this mistake ; so it is an error by the character, not a Character Error goof by the film-makers.

There's a scene during the credits, showing real footage of the trio in a parade in Sacramento. Texts on screen tell us that they were all awarded medals.
