The Teenage Mutant Ninja Turtles save Los Angeles rail transit in "Operation Blue Line" (1990)

As a Teenage Mutant Ninja Turtle enthusiast in childhood and a Los Angeles rapid transit enthusiast in adulthood, I should, by all rights, love Operation Blue Line, a ten-minute 1990 promotional video wherein the usually New York-based Heroes on a Half Shell defeat Gridlock, a villain bent on "suppressing all public information" about the Blue Line, the first branch of the city's modern rail system.
