Investigators Friday were trying to identify a man fatally struck by a SEPTA commuter train near the Pennbrook station in Lansdale.
The victim was between 55 and 60, said Montgomery County Coroner Walter I. Hofman. He was white with graying hair, somewhat balding.
The man was wearing a wedding ring and jogging suit or workout clothing, Lansdale Police Chief Robert McDyre said. No identification was found at the scene.
With so little to go on, investigators have pinned their hopes to an Infiniti key fob that the man was carrying, Hofman said.
Investigators have contacted an Infiniti office in California and are waiting for company officials to match the fob's signal to a particular vehicle identification number.
Once investigators have the number, they can find the owner through vehicle records.
Hofman said he thought the man might have been married for a second time, since the date engraved on the ring was 15 years ago. He would not reveal the initials in the engraving.
"I can't tell you much," Hofman said Friday. "We're still looking. "
The fatality occurred at 7:40 a.m., said Jerri Williams, spokeswoman for SEPTA. She said the man was seen near the tracks just north of the station on the Lansdale/Doylestown Regional Rail line. The station is at Pennbrook Parkway and Church Road.
Hofman said investigators were trying to find the car that matched the fob. They were also looking at the contents of a flash drive found on the tracks.
Hofman said the engineer saw the man and blew the train's horn, but the man did not move.
"Unfortunately, the engineer was not able to stop in time," Williams said.
Hofman said he would not determine whether the death was an accident or suicide until investigators reconstruct what happened.
Anyone with information is being asked to contact Lansdale police at 215-368-1801.
