BURBANK, CALIF. — A fitness model and actor who previously shot workout videos on railroad tracks was struck and killed by a train during filming in Southern California.

Two men were videotaping George Plitt Jr., 37, on the tracks north of the Burbank train station Saturday afternoon when Plitt was hit by a Metrolink passenger train, Burbank Police Sgt. Scott Meadows said Sunday.

Investigators have ruled out a suicide, and were trying to determine who directed the men to film in a restricted area of the tracks. They have interviewed witnesses who saw Plitt standing on the track even as the train’s horn was blaring, Meadow 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.

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.
