Operation Blue Line, Starring: Teenage Mutant Ninja Turtles was a 1990 promotional video released by Family Home Entertainment and sponsored by the Southern California Rapid Transportation District to let kids know about alternative travel methods such as railroads. It is live-action, but due to the budget, this does not use animatronics. Instead the actors who played the Turtles simply wore toy-style mascot costumes. The voice actors from the 1987 TV series reprise their roles as the Turtles.
