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 (PRR) completed construction of the yard in 1910; it was originally the largest coach yard in the world, occupying 192 acres (0.78 km2).

Harold Interlocking, the United States' busiest rail junction, is part of the yard. The shared tracks of the Long Island Rail Road (LIRR) Main Line and Amtrak's Northeast Corridor pass along the southern edge of the yard. Northeast of the yard a balloon track (or reverse loop) 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.

History
The Pennsylvania Railroad (PRR) completed construction of the yard in 1910. At that time, Sunnyside was the largest coach yard in the world, occupying 192 acres (0.78 km2) and containing 25.7 miles (41.4 km) of track.  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.

Plans

East Side Access project

As part of the East Side Access project to the new LIRR terminal at Grand Central Terminal (opened January 25, 2023), some LIRR trains diverge from the main line and travel through a tunnel under the yard. The project would also create a new station at Queens Boulevard, named Sunnyside.

Harold Interlocking

In May 2011, a $294.7 million federal grant was awarded to address congestion at Harold Interlocking, the United States' busiest rail junction, which is part of the yard. The work will allow for dedicated tracks to the Hell Gate Line right of way for Amtrak trains arriving from or bound for New England, thus avoiding NJT and LIRR traffic. Some of the interlocking improvement projects are complete as of early 2023. Other projects are ongoing and will be complete by late 2025.

Housing development

In 2017 it was announced that the city would begin a feasibility study into the construction of 21,000 to 31,000 units of housing on top of the rail yard. The project, which would be similar to the Hudson Yards development over West Side Yard, has stoked public controversy over the affordability of units, pedestrian and road connections, open space, and a nearby Superfund site.  In Sept. 2019, a public meeting was interrupted by protestors chanting, "We Don't Trust this Process!" In early 2020, Amtrak and the city government published a master plan. The plan called for building a deck over Sunnyside Yard and constructing 12,000 housing units, all of which would be affordable housing, as well as  of parks and public plazas.
