Станция 15th Street/City Hall: История и Реконструкция

Rapid transit station in Philadelphia
The station is in the very heart of Center City Philadelphia. City Hall lies across the street from the station, and attractions as Love Park, the Penn Center area, and the Comcast Center are within walking distance.

15th Street was the original eastern terminus of the Market–Frankford subway–elevated, which was opened by the Philadelphia Transportation Company on August 3, 1907, and ran west to 69th Street in Upper Darby. In 1908, the Market–Frankford Line was extended eastward to Market Chestnut (now closed), meaning 15th Street was no longer the eastern terminal. In 1936, an underground concourse opened connecting the 15th Street to City Hall station, which opened eight years previously along with early portions of the Broad Street Line. SEPTA and the City of Philadelphia had been proposing a $100 million refurbishment of City Hall station, which included structural repairs, improvements in lighting and ventilation, aesthetic improvements, as well as ADA improvements; however, this project's progression had stalled due to lack of available funding. In November 2011, the Central Philadelphia Development Corporation awarded construction contracts totaling $50 million for the restoration of Dilworth Park above the station, following the eviction of the Occupy Philly protesters occupying the area; this contract includes the accessibility improvements for the station. SEPTA awarded construction contracts for the improvements in January 2012. Phase 1 of project consisted of a restoration of the Dilworth Park plaza, creating a "gateway" to the SEPTA transit station and installing elevators connecting to the street and Market–Frankford platforms at 15th Street. Later phases upgraded 15th Street station, City Hall station, and inter station connections, and made them ADA compliant. The renovated Dilworth Park opened on September 4, 2014. In 2013, the passage of PA Act 89 (Transportation Funding Law) has allowed SEPTA to move forward with the $147 million BLT Architects designed renovation of the 15th Street/City Hall station complex. Construction at 15th Street station began in 2016 and was expected to be complete in 2018, with the reconstruction of City Hall station beginning in 2019. Construction at 15th Street station concluded on October 21, 2019. In addition to new elevators and other infrastructure upgrades, the Market–Frankford platforms received new LED illuminated artwork by Ray King. The remaining two phases of the project, which will upgrade City Hall station and the corridors between the two stations, is yet to be completed.

The Market–Frankford Line platforms are attached to the Downtown Link concourse, a series of underground pedestrian walkways that provide access to SEPTA Regional Rail's Suburban Station, the Broad Street Line's Walnut–Locust stations, the PATCO Speedline's 12–13th & Locust and 15–16th & Locust stations, and the Market–Frankford Line's own 13th Street, 11th Street, and 8th Street stations. However, no free interchange is available to any of these stations. Only the City Hall station on the Broad Street Line can be accessed inside fare control.

All five subway–surface trolley lines stop at 15th Street station. The trolley platforms are located on either side of the Market–Frankford Line tracks, with the inbound platform south of the MFL and the outbound platform north of it. Because the platforms are located within fare control, riders do not need to tap SEPTA Key cards upon boarding the trolleys like some of the other underground trolley stations.

There are four side platforms, two high level for the Market–Frankford Line and two low level for the subway–surface trolley lines. The trolley tracks are located slightly below the grade of the Market–Frankford Line tracks, as trolleys loop underneath the MFL at 13th Street station.
