Responders "originally thought they'd find the body elsewhere after finding the arm" near the Anderson Street station around 10:15 p.m., Hackensack Police Capt. Timothy Lloyd said.
"He apparently tried to walked home" and made it four blocks to Second Street, said Lloyd, the department's officer in charge. "They were searching the tracks when he called in."When police showed up, he answered the door.
The man, who responders said has a history of mental issues, was taken to Hackensack University Medical Center, along with the arm.
Chances were unlikely that it could be reattached, a responder with direct knowledge of the situation told Daily Voice as the man went into surgery.
"They'll probably close it up," he said, adding that the man appeared heavily drugged. "It looks like he's going to live."
NJ Transit dispatched buses to collect the 200 passengers, the agency's Jennifer Nelson said.
None of them nor any crew members on the 9:42 p.m. No. 1645 Pascack Valley Line train out of Hoboken to Spring Valley was injured, she told Daily Voice.
