METRO says the incident happened on October 16, 2016, but didn't provide any further information.
The video was posted on YouTube with the caption, "Moms and Dads, we appreciate everything you do, and we urge you to talk to your kids about rail safety. Remember, our trains weigh about 50 tons, which is the equivalent of seven fully-grown African Elephants! They can't easily or quickly stop even if traveling slowly. Keep this in mind when a train is approaching a platform."
