The F train cars that derailed Friday in Queens, injuring 19, were removed over the weekend, allowing crews to repair the damaged track with the goal of having full service to the F and E lines by today’s morning rush at 5 a.m., the MTA said Sunday.
The trains were removed early Sunday morning and E and F trains were running local beginning at 7 a.m.
“The challenge here was getting a derailed train out of the way,” said MTA spokesman Adam Lisberg.
Investigators are looking into a fractured rail at the site that was manufactured in November and installed two months before the derailment, the agency said.
“At this point it becomes a scientific investigation to look at everything that happened to that rail in the weeks since it was installed and also look at everything about the train car that went over it,” Lisberg said.
Track inspectors twice a week walk through the subway system and do a visual check for potential flaws, while cars with specialized equipment scan for defects in the rail and issues with installation every other month, according to Lisberg, who did not have details about when exactly the site of the derailment received such inspections.
“The records of all the recent inspections will be part of the investigation,” he said.
The eight-car train derailed in Woodside, near the 65th Street station. The middle six train cars left the tracks but the train did not fall over. About 1,000 people were evacuated and 19 hurt.
The derailed train cars were taken to Jamaica rail yard, where they will be examined, according to MTA spokeswoman Amanda Kwan.
Kwan said yesterday that investigators were still working to determine the cause of the derailment, and both the MTA and the state’s Public Transportation Safety Board were involved.
“The age of the tracks is not a factor. Speed is not a factor,” she said. “There was a broken rail. We do not know if that’s the cause, but we need to find out how and why it was broken.”
