(DC)- Metro says it will continue to stay open late if necessary to help fans get home from the upcoming World Series games at Nationals Park. This postseason Metro has kept the Navy Yard station near the stadium open for at least 20 minutes after every postseason home game and will continue to do so during the World Series. Officials say if the series makes it to Game Five, they would extend the Metro hours as the matchup takes place on Sunday, when the system closes at 11 p.m. Metro says it costs roughly 100-thousand dollars an hour to keep the system open.
