MANHATTAN — A smoky fire broke out in a train tunnel north of Grand Central Station Tuesday evening, leaving one person injured and causing brief delays for commuters, officials said.
According to sources, sparks erupted from the ceiling on the north end of tracks 28 and 29, near 51st Street, at 6:16 p.m.
The blaze sent smoke into Grand Central as well as the basement of 320 Park Ave., according to a police officer at the scene and fire officials.
One person suffered smoke inhalation and the FDNY was monitoring the site for carbon monoxide.
Grand Central was not evacuated or affected by the smoke, said MTA spokesman Sam Zambuto.
The cause was under investigation, but the fire "may have resulted from electrical arcing" on the ceiling, Zambuto said.
The fire caused temporary delays of up to 30 minutes on southbound and 10 to 15 minutes on northbound Metro-North trains on the Hudson, Harlem and New Haven lines, the MTA said on its website.
Those delays were cleared by 7:45 p.m.
