Late-Morning Jolt: Subway Derailment in Queens Injures 19

The F train slithered across Woodside, Queens, without incident at first, its passengers bound for jobs and late-morning appointments in Manhattan and Brooklyn.

But as the train hurtled past the 65th Street station around 10:30 a.m., passengers said, the ride turned earthquakelike: Standing passengers tumbled to the floor, the train ground to a stop and travelers peered through the car windows to find themselves listing to the left of the tracks.

The authorities said the middle six cars on the eight-car train had derailed, causing 19 injuries — four “potentially serious,” according to the New York Fire Department — and setting off a wide-scale effort to reach about 1,000 passengers who were stranded underground.

基本の基本ですが、groundはgrindの過去形です。ground to a stopで車輪がキッーという音を立てて停止したとなります。以前、同じ様な事故を伝える記事を授業で扱い、groundに-edが付いていない、記者の間違いではないのでしょうか、とUG先生に質問したことがあります。恥ずかしい思い出です。（GP）
