Transit officials say a section of rail that snapped and caused a New York City subway train to derail had been installed just weeks ago.
The Metropolitan Transit Authority said Saturday that the rail that broke underneath an F train in Queens on Friday was manufactured in the U.S. in November. It was installed in March.
The MTA says other rails from that shipment will be inspected.
About 1,000 commuters were on board the train when it rode off the rails at 10:15 a.m.
Nineteen people were injured, four seriously. Several hundred were trapped on the train below ground for hours.
MTA workers are repairing a damaged 500-foot stretch of rail and aim to have local service restored by Saturday afternoon.
