Cedar Hill Yard is a classification yard located in New Haven, North Haven and Hamden, Connecticut, United States. It was built by the New York, New Haven and Hartford Railroad in the early 1890s in and around New Haven's Cedar Hill neighborhood, which gave the yard its name. To handle increasing traffic as a result of World War I, the yard was greatly expanded between 1917 and 1920 with additional construction along both sides of the Quinnipiac River. The yard was further modernized in the 1920s, becoming one of the busiest railroad yards in the United States, and the most important yard in the entire New Haven Railroad system. At its peak during World War II, Cedar Hill Yard handled more than 5,000 railroad cars per day.
