Gantry State Park in Hunters Point is undergoing yet another expansion and reconfiguration, which has already added a new ferry terminal. Even before those changes, though, the park has laid rusty railroad tracks here and there. Decades ago, a rail spur ran from Sunnyside Yards between 48th and 49th Avenues to the waterfront, where float barges unloaded goods for transport into the heart of Long Island. The LIRR once had substantial freight operations that have slowed to a trickle of what they once were.
