The accident occurred at about 12:30 a.m. Monday about a half-mile west of the South Norwalk station, Anders said. The train involved was bound for New Haven.
"It was initially reported as striking debris, which happens quite a bit," she said. "They stopped the train and got out but didn't see anything. ... About an hour later a track supervisor found the body."
No identification was found, Anders said. The victim was identified as a woman in her late 20s or early 30s.
The accident remains under investigation, she said.
The Monday morning commute was not affected, she said.
