In 1951, the growing subway network was the setting of "A Subway Named Mobius", a science fiction short story written by the American astronomer Armin Joseph Deutsch. The tale described a Boston subway train which accidentally became a "phantom" by becoming lost in the fourth dimension, analogous to a topological Mobius strip. In 2001, a half-century later, the narrative was awarded a Retro Hugo Award for Best Short Story at the World Science Fiction Convention.

In 1959, the satirical song "M.T.A." (informally known as "Charlie on the MTA") was a hit single, as performed by the folksingers the Kingston Trio. It tells the absurd story of a passenger named Charlie, who cannot pay a newly imposed 5-cent exit fare, and thus remains trapped in the subway system. The song was still well known in 2006, when the MBTA named its new electronic farecards the "CharlieCard" and "CharlieTicket".
