Park near the Kew Gardens Interchange. It has served as the primary storage yard for the IND Queens Boulevard Line since its opening in 1936. The yard connects to the Queens Boulevard Line at a three-way flying junction just geographically north of the Kew Gardens–Union Turnpike station. The yard is at surface level, and the four-track approach includes a bridge over the Grand Central Parkway; though the Queens Boulevard Line is underground, the yard lies at a lower elevation than the subway. The property on which the yard sits used to belong to the Department of Water Supply, Gas, and Electricity, and it was transferred to the New York City Board of Transportation on April 2, 1930. The property was used as a pumping station, and once the Board of Transportation acquired the property, wells that were abandoned on the property were disturbed. These wells were connected to the water mains serving Forest Hills, Kew Gardens, and part of Flushing. $50,000 was appropriated to replace these water wells and mains by the Board of Estimate. Originally, the yard was intended to be built in the vicinity of South Elmhurst and Rego Park at Grand Street and Queens Boulevard. Once the location near Union Turnpike was decided, the communities of Forest Hills and Kew Gardens objected to it, arguing that the values of their properties would go down and the growth of the communities would end. Chairman of the Board of Transportation, John H. Delaney, overruled them, as the yard's location was not near any homes. The yard was built for the Independent Subway System in the 1930s. Work was half finished on Jamaica Yard in April 1935, and the total cost of Jamaica Yard and storage sheds was approximately $560,000. Jamaica Yard served as the south end of the IND World's Fair Line which served the 1939 New York World's Fair from 1939 to 1940. In August 1964 it was planned that Jamaica Yard have car-washing machines installed in May 1965. The yard is home to the 5-car sets of R160s, assigned to the , , , and , whose carwash, interior cleaning, grease and minor repair services are provided by the yard. Some R160As for the are stored here as well during weekdays, but are not maintained here, as the M uses shorter, four-car sets maintained at East New York Yard.
