Sunnyside Yard
Sunnyside Yard is a large coach yard, a railroad yard for passenger cars in the Sunnyside neighborhood of Queens in New York City. The yard is owned by Amtrak and is also used by New Jersey Transit. The Pennsylvania Railroad completed construction of the yard in 1910; it was originally the largest coach yard in the world, occupying 192 acres.
Harold Interlocking, the United States' busiest rail junction, is part of the yard. The shared tracks of the Long Island Rail Road Main Line and Amtrak's Northeast Corridor pass along the southern edge of the yard. Northeast of the yard a balloon track is used for "U-turning" Amtrak and NJ Transit trains which terminate at Penn Station. Leading eastward near the south side of the yard, this balloon track switches off and turns left under the LIRR/Amtrak tracks, turns left once again, and merges with the Sunnyside Yard track to turn the train west toward Penn Station.

The yard served as the main train storage and service point for PRR trains serving New York City. It is connected to Pennsylvania Station in Midtown Manhattan by the East River Tunnels. The Sunnyside North Yard initially had 45 tracks with a capacity of 526 cars. The South Yard had 45 tracks with a 552 car capacity.Factories surrounded Sunnyside Yard. On the south side the Degnon Terminal rose, with businesses served by the railroad. It included the American Chicle company factory for chewing gum, the Eveready Battery Company factory for batteries, and the Loose-Wiles Sunshine Biscuits factory. The Swingline Stapler factory was immediately east of there, at 32-01 Queens Boulevard.
