The Taking Of Pelham One Two Three (1974)

"Gesundheit."

Hijackers take control of a New York subway train and demand $1m in return for the release of their hostages. Fun fact one - the criminals refer to each other using colours, as copied in Reservoir Dogs. Fun fact two - there's a remake coming out next year, starring Denzel Washington and John Travolta in the Mr Blue role (previously played by Robert Shaw, shown above). IMDB
