full_context: Document 1: East Falls, Philadelphia: East Falls is a neighborhood in the Northwest section of Philadelphia, Pennsylvania, United States on the east or left bank side of the now submerged Schuylkill River cataracts, the 'Falls of the Schuylkill' that became submerged as the Schuylkill Canal and Fairmount Water Works projects were completed in 1822. The East Falls community is located adjacent to Germantown, Roxborough, Allegheny West, and Nicetown-Tioga neighborhoods. East Falls is also adjacent to Wissahickon Valley Park. The neighborhood runs along a stretch of Ridge Avenue that is only a few miles long, along the banks of the Schuylkill River then extends northeast to Wissahickon Avenue. East Falls overlooks the multi-use recreational path of Fairmount Park along Kelly Drive, and is desirable for its central location, an easy commute to Center City, with easy access to several major roadways and public transportation. East Falls continues to develop, with new housing, retail space and recreation centers in production. It features three streets in proximity with the word "Queen" in them (Queen Lane, New Queen Street, and Indian Queen Lane), two train stations, a number of bars and restaurants, a small Korean grocer, illustrious mansions as well as some recently renovated housing that continues to increase in value.
Document 2: Broad Street Line: The Broad Street Line (BSL)—also known as the Broad Street Subway (BSS), Orange Line, or Broad Line—is a subway line owned by the city of Philadelphia and operated by the Southeastern Pennsylvania Transportation Authority (SEPTA). The line runs primarily north-south from the Fern Rock Transportation Center in Upper North Philadelphia to Pattison Avenue in South Philadelphia; the latter station provides access to the stadiums and arenas for the city's major professional sports teams, about a quarter mile away. It is named for Broad Street, the street under which it runs for almost its entire length. The line, which is entirely underground except for the northern terminus at Fern Rock, has four tracks in a local/express configuration from Fern Rock to Walnut-Locust and two tracks from Lombard-South to the southern terminus at AT&T Station (formerly Pattison Station). It is one of only two rapid transit lines in the SEPTA system overall alongside the Market–Frankford Line.

Document 4: Philadelphia to Harrisburg Main Line: The Philadelphia to Harrisburg Main Line is a rail line owned and operated by Amtrak in the U.S. state of Pennsylvania.

Document 8: Liberty Place: Liberty Place is a skyscraper complex in Philadelphia, Pennsylvania, United States.

Prior to the construction of Liberty Place, there was a "gentlemen's agreement" not to build any structure in Center City higher than the statue of William Penn on top of Philadelphia City Hall. The tradition lasted until 1984 when developer Willard G. Rouse III of Rouse & Associates announced plans to build an office building complex that included two towers taller than City Hall. There was a great amount of opposition to the construction of the towers with critics believing breaking the height limit would lead to construction of many more tall skyscrapers, ruining the livability and charm of Center City. Despite the opposition, construction of One Liberty Place was approved and the first phase of the project began in 1985 and was completed in 1987. When One Liberty Place was completed, it was the tallest skyscraper in Philadelphia.

Document 11: List of SEPTA Rapid transit stations: The Southeastern Pennsylvania Transportation Authority contains two major rapid transit lines; The Market–Frankford Line and the Broad Street Line, both of which were inherited from the former Philadelphia Transportation Company, and originally built by the Philadelphia Rapid Transit Company.

Document 12: Race–Vine station: Race-Vine is a rapid transit passenger rail station on SEPTA's Broad Street Line. It is located at 300 North Broad Street (PA 611) in the Center City district of Philadelphia, and serves both local and express trains. The station is named after Vine Street, which today acts as frontage roads along Interstate 676 and nearby Race Street, although the given address is closer to westbound Vine than Race. This stop is also used as the Pennsylvania Convention Center stop for the Broad Street Line (signs will direct passengers to the appropriate exits, although riding the Broad Street Line one stop further south to City Hall and then connecting to the Market–Frankford Line East toward Frankford and then exiting at 11th Street station will bring passengers right inside the Convention Center and The Gallery at Market East).

Document 15: 37th Street station (SEPTA): 37th Street station, also known as the 37 Street/Spruce Street/Woodland Avenue station, is a SEPTA Subway-Surface Lines trolley station in Philadelphia. It is the last station in the tunnel before the 40th Street Portal and carries Subway-Surface Trolley Routes 11, 13, 34, & 36. The entrance to go down into the eastbound side of the station is on the campus of the University of Pennsylvania and the entrance to go down into the westbound side of the station is on Spruce Street. The two stations are off set and are not on the same length of the track. Trolleys serving this station go eastbound to Center City Philadelphia and Westbound to the Philadelphia neighborhoods of Eastwick and Angora and the Delaware County suburbs of Yeadon and Darby. The reason why the station platforms are off set is because during construction of the subway station the above intersection was Spruce & 37th Streets at Woodland Avenue with all three streets crossing at a five points intersection. Upon entering the subway, 37th Street's westbound platform is passed first, the exit/entrance was built on the north side of Spruce Street, and the eastbound couldn't be on Spruce Street because it would have placed the subway exiting stairs in the middle of Spruce Street, so the eastbound platform exit/entrance was placed on the far side of Woodland Avenue (now Woodland Walk).
