July 29 (Bloomberg) -- PATH train service between the World Trade Center station in Manhattan and Newark, New Jersey, was restored shortly before 8 p.m. local time after signal problems halted trains for about four hours.

The New York City Office of Emergency Management said in a statement that signal problems caused the system to shut down at about 4:15 p.m. local time. More than 240,000 travelers take the PATH, or Port Authority Trans-Hudson, service daily.
