NEW YORK DAILY NEWS • Once a hero, always a hero. A Queens man who made headlines in 2013 when he jumped onto subway tracks to rescue an elderly man has started a nonprofit dedicated to helping children in his native Honduras. “My life has changed for the good since the train incident,” said Ramiro Ocasio, 35, of Astoria. “I had no idea.” The quick-thinking straphanger made the daring dive on Jan. 18 after an elderly man tumbled onto the subway bed at the busy Lexington Ave./59th St. station in Manhattan.
