A vacant five-story apartment building collapsed in New York Tuesday, leading to the suspension of dozens of rush-hour suburban trains amid fears the vibrations could cause more bricks to fall.

According to New York fire officials, no one was injured when the building on East 124th Street near Park Avenue in upper Manhattan crumbled around 3 p.m. The building was a block away from the 125th Street Metro-North station. Thousands of train commuters were affected, their route being either canceled, crowded or slowed. The traffic to and from New York’s Grand Central Terminal was partially restored a few hours later but trains were halted as authorities checked for debris, Dan Brucker, a representative for the Metropolitan Transportation Authority said, according to CNN.

Nearly 270,000 riders use Metro-North on weekdays, MTA Web site reports.

The cause of the collapse had not been determined, Michael Alacha, an assistant commissioner of the Buildings Department said.

A spokesperson for building owner Jared Kushner, of the Kushner Co., said that before the collapse the owner initially had planned to rehabilitate the building, which had been vacant for six months, and one next to it. Then, bricks began falling from the building two days ago. Engineers for the Buildings Department visited the site, deemed the buildings unsafe and contracted city officials to get permission to begin demolishing them on Wednesday, spokesperson Howard Rubenstein said.

The partial collapse happened while inspectors from the buildings and fire departments were at the site. A demolition crew was dispatched to take down the remainder of the building, as well the one next to it, fire officials said.
