A Metro train operator is under investigation after a video surfaced showing the driver apparently talking to a rider while running a Yellow Line train. The YouTube video, first reported by NBC4, shows a person perched on a seat by the operator’s door, head ducked inside the opening to the cab at the front of the train. The agency learned of the video Monday and began investigating the case, Metro spokesman Reggie Woodruff said Tuesday.

“Train operators are required to focus on the safe operation of the train, and we immediately followed up with our employee to address what appears to be an incident in which an operator is distracted,” he said.
