Two men were filming George Plitt Jr on the railroad track north of the Burbank train station Saturday afternoon when Plitt was hit by a southbound train, said Burbank Police Sergeant 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.
Plitt also went by the name Greg and was a well-known fitness model, he said.
The actor and West Point graduate has appeared on more than 200 magazine covers, Bravo's reality television show "Work Out" and NBC's daytime soap opera "Days of Our Lives," according to a website in Plitt's name.
