Greg Plitt

BURBANK, Calif. – A fitness model and actor featured on the cover of numerous fitness magazines was struck and killed by a train while filming on the tracks in Southern California, authorities said Sunday. Two men were filming George Plitt Jr., 37, on the railroad track north of the Burbank train station Saturday afternoon when Plitt was hit by a Metrolink passenger train, said Burbank Police Sgt. Scott Meadows. Investigators, who interviewed witnesses who saw Plitt standing on the track even as the train's horn was blaring, have ruled out a suicide, he said. It appears Plitt may have believed the train was on a nearby, parallel track, Meadows said. "It's like a blind turn," he said. "When the train came, you might not be able to tell which set the train is on." It was not immediately clear what the men were filming. Investigators are trying to determine who directed them to film on the railroad track. The men were in a restricted area on the tracks, Sgt. Mark Stohl said. Plitt also went by the name Greg and was a well-known fitness model. The actor and West Point graduate has appeared on more than 200 magazine covers, Bravo's reality television show "Work Out" and "Friends to Lovers" and NBC's daytime soap opera "Days of Our Lives," according to a website in Plitt's name. A motivational video on the website shows Plitt working out on the tracks as a Metrolink train passes by. Plitt was born in Baltimore. He served five years in the Army after graduating from West Point, the website said.
