BROOKLYN - Subway service is running smoothly after a two-alarm fire shut down Brooklyn trains during the Tuesday night rush hour commute.

Officials say cables caught fire under the subway tunnel at the Dekalb Avenue station in downtown Brooklyn, creating a smoke condition that shut down service on the B, D, N, Q and R lines.

It took more than 100 firefighters about two hours to get the flames under control. The FDNY says there was one minor injury and commuters were never at any risk.
