Is it a myth that the real outlaws of the old west never robbed a train on horseback?

To this day Hollywood has never {"Unstoppable" included} ,never NEVER , come close to accuracy in dealing with trains in movies . The few actually close to reality , are so few and far between that they are unknown to all , but those who love trains . So.Know this to be true -If you saw it in a movie, it's a deception! An exaggerated falsehood , A great fat lie.
