A five-story vacant apartment building partially collapsed in upper Manhattan, leading to the suspension of dozens of rush-hour suburban trains. There were no immediate reports of injuries.

Metro-North spokeswoman Suzanne Lopez said the collapse occurred near 124th Street and Park Avenue in East Harlem. She said trains were being held at all stations, including Grand Central Terminal and at 125th Street, a block away from the building.

New York City Buildings Department spokeswoman Kate Lindquist says two of the building's walls and several interior floors partially collapsed. Buildings inspectors and forensic engineers were on the scene.

Railroad spokeswoman Marjorie Anders said the trains were stopped at stations so passengers could get off if they wished.
