An explosion at the MTA's 207th Street Yard in Inwood, Manhattan on Tuesday night injured nine people, who were evaluated by EMS.

Why it matters
An explosion at the MTA's 207th Street Yard in Inwood, Manhattan (near 212th Street and 10th Avenue) on Tuesday night (Oct. 13) injured nine people, who were evaluated by emergency medical services. According to FDNY radio traffic, all nine were triaged as minor injuries (green tags).
FDNY on-scene radio traffic indicates the blast came from a halon fire-suppression system inside a yard building that overpressurized and burst, collapsing pieces of concrete. CBS2 reported nine people hurt; Streetsblog's Thursday headlines (citing Patch) also picked up the incident, placing the explosion at the MTA's 207th Street Yard.
Background
The 207th Street Yard is a major subway yard at the northern end of Manhattan. Halon suppression systems, common in equipment rooms, extinguish fires with high-pressure gas; an overpressure burst points to equipment failure, and the exact cause awaits further word from the MTA and fire officials. There were no immediate reports of major disruption to subway service.
