Line 52:
The two Archer Avenue lines begin at a northern (geographic eastern) terminal, [[Jamaica Center–Parsons/Archer (Archer Avenue lines)|Jamaica Center–Parsons/Archer]] ({{NYCS trains|Archer}}), as a bi-level subway, each level having two tracks. The upper level is used by the B2 ([[IND Division]]) Archer Avenue line, and uses IND radio frequencies, while the lower level is used by the B1 ([[BMT Division]]) Archer Avenue line, and uses BMT radio frequencies.<ref name="tracks">{{NYCS const|trackref|trackbook3}}</ref> The two lines run compass west along Archer Avenue to another station at [[Sutphin Boulevard–Archer Avenue–JFK Airport (Archer Avenue lines)|Sutphin Boulevard–Archer Avenue–JFK Airport]], where connections can be made to the [[Long Island Rail Road]] and [[AirTrain JFK]].<ref name="MTAJamaicaMap-20152">{{Cite NYCS map|neighborhood|Jamaica}}</ref> West of this station, the two levels diverge. The lower level tracks ({{NYCS trains|Archer lower}}) continue roughly compass northwest, emerging from a portal near 89th Road and 130th Street and paralleling the [[Main Line (Long Island Rail Road)|Main Line]] of the LIRR before turning west onto the elevated structure of the [[BMT Jamaica Line]] at about 127th Street.<ref name="MTAJamaicaMap-20152" /> The upper level tracks ({{NYCS trains|Archer upper}}) turn compass north under the [[Interstate 678|Van Wyck Expressway]], with [[Jamaica – Van Wyck (IND Archer Avenue Line)|another station]] at [[Jamaica Avenue (Queens)|Jamaica Avenue]].<ref name="MTAJamaicaMap-20152" /> Just north of [[New York State Route 25|Hillside Avenue]], they meet the four tracks of the [[IND Queens Boulevard Line]] at a [[flying junction]], with connections to both the local and express tracks.<ref name="tracks" />
[[Jamaica Center–Parsons/Archer (Archer Avenue lines)|Jamaica Center–Parsons/Archer]] was not intended to be the lines' northern terminal, as there are spurs on both levels for possible future extensions. On the lower level, they continue one train length and end at [[bumper block]]s.<ref name="tracks" /> This was a planned extension toward Hollis.<ref name="MTA-ArcherAvDEIS-19732">{{cite book|url=https://books.google.com/books?id=Wd43AQAAMAAJ|title=Archer Ave Route (proposed) Construction, Queens: Environmental Impact Statement|date=August 1973|publisher=[[Urban Mass Transit Administration]], [[United States Department of Transportation]]|access-date=August 6, 2016}}</ref><ref name="int-arch22">{{cite book|url=https://archive.org/details/metropolitantran00newy|title=Metropolitan transportation, a program for action.
