The woman who was struck and killed by a train in Rockville on Friday, at the same grade crossing where two other people have committed suicide in the last three years, has been identified as Elizabeth Woodward Feroldi, 40, of Vienna, police said yesterday.

Montgomery County police said Feroldi, of the 9800 block of Hidden Estates Cove, had committed suicide.

Investigators said Feroldi was hit by Amtrak's eastbound Capitol Limited about 3:45 p.m. where two sets of tracks cross Randolph Road near Nebel Street.

Last week, police said witnesses told them Feroldi appeared to be looking through binoculars or a camera at the train as it approached. Yesterday, police spokesman Derek Baliles said investigators found a pair of binoculars near the tracks. No camera was found.

A man who answered the phone at Feroldi's home and identified himself as a relative said, "We have no comment at this time."

Baliles said police were certain the death was a suicide.

"She had put the binoculars up to her eyes," he said. "She had done that multiple times. . . . The witnesses were very consistent in saying that she deliberately put herself in the path of the oncoming train."

She left no suicide note, Baliles said.

The incident happened at the same crossing where Maribel Gonzalez, 23, of Rockville, clutching her 2-year-old daughter, Pamela, stepped in front of the same Amtrak train about the same time on June 6. Both were killed. Gonzalez committed suicide, officials ruled.

Three years ago, a 24-year-old man killed himself by stepping into the path of a MARC commuter train on the same tracks, officials said.
