PATCO Speedline trains operated on an emergency schedule between Philadelphia and Camden County, New Jersey, for hours Thursday after a derailment.
The Port Authority Transit Corporation says a piece of contractor equipment derailed Thursday west of the Lindenwold Station. No one was injured.
Local trains only ran every 15 to 20 minutes during the morning rush.
Trains would run every 20 minutes through the day, PATCO said.
PATCO restored full service by 2 p.m.
