All Metro-North trains servicing New York's suburbs have stopped running this evening due to what the MTA is calling "signal issues" that appear to relate to either a power outage, according to NBC's Gus Rosendale; or a computer glitch according to CBS.
CBS adds the outage has persisted for at least two hours.
Metro-North is America's third-busiest rail service. So things are getting really ugly.
Here's what Grand Central looks like right now:
