The FDNY said the fire was in an area of temporary wiring used for lighting in an underground construction site at 34th Street and Eighth Avenue.
The fire began on the first floor of the home on Tioga Drive in the St. Albans neighborhood at about 7 p.m., authorities said. The brothers were discovered unconscious on the second floor, police said.
The derailment happened on the express tracks around 10:40 a.m. in a tunnel about 1,200 feet south from the 65th Street station in Woodside.
Two maintenance workers were stuck in wind gusts outside the 45th floor of the 600-foot-tall Hearst building when the scaffold they were working on collapsed at about 2:40 p.m.
Two scaffold maintenance workers trapped for more than an hour on a collapsed scaffold high above the streets of Midtown Manhattan have been rescued.
Twenty-one adults and six children are homeless, some from four-story brownstone and others from neighboring buildings that were also evacuated as crews prepare to tear the building down.
