A pooch jumped onto the tracks last evening and marched in front of two trains - which crawled after it at about 5 mph. The crew of the first train tried to scare it away by blasting the horn, but the pooch wasn't impressed. It continued to lead its parade of laughing passengers four miles from Jamaica to Laurelton, Queens. The ride, which normally takes seven minutes, lasted an hour. The Long Beach and Far Rockaway line trains, carrying a total of about 800 people, were an hour late. "Everyone's laughing," said passenger Allen Cohen, of Long Beach, who spoke to The Post from his cell phone. " 'The dog is growling at the train' - this is what they announced," sighed Cohen. "When they get too close to the dog, it turns and growls at the train. People are saying you couldn't make this up." Some passengers abandoned ship at Laurelton, while others waited until the tracks were clear. Cohen eventually spied the dog sitting quietly with a leash around its neck, and two people holding it. It's not clear who captured the dog or where they took it. "It's New York, that's what it is," he said. "It's just another crazy situation in New York." The dog was the city's second recent canine commuter. On Christmas Eve, a pooch jumped aboard a Metro-North train in Connecticut, and was collared by a passenger who took it to a shelter.
