The video shows a man lunging at another, then jumping, screaming, and turning on the woman and shoving her headfirst into the idling train. It happened Wednesday.
Police say Isaiah Thompson was arrested on Thursday on assault and other charges. Information on his lawyer wasn't available.
The 28-year-old Thompson was arrested in May after police said he was the man seen on a video pulling a train's emergency brake and fleeing.
Police believe Thompson is responsible for dozens of similar brake-pulling stunts that caused extensive delays.
