Well, technically the temporary shuttle line that will serve the Rockaways until the hurricane-ravaged A train gets fixed isn’t a subway, exactly, since it travels entirely above ground. And technically it’s not new — the H train existed up until 2004, when it was merged with the A train. But, okay, it’s a newish train. It’s also, we just learned, a slang term for doing heroin, at least according to Urban Dictionary, where every word or phrase is a slang term for some kind of drug or sexual maneuver.
