The main line of the Philadelphia and Reading railways (the original Philadelphia and Columbia Railroad and Northern Liberties and Penn Township Railroad) pass through Philadelphia on the southwest side of the Schuylkill River northwest of the city center (this line is now only used for freight trains). Then it passes through the tunnel below Pennsylvania Avenue and turns north-east from Callowhill Street. then turn to the south along the Broad Street, where the station is located. This line continues eastward to the Delaware River, passing through Willow Street.

The passenger station was later moved a little further away from the Wire Street, or the old cargo line. The second reading line, led by Philadelphia, Germantown and Norristown Railroad, now uses the SEPTA Passenger Service. This line passed northeast of the 9th street to the east-west on Willow Street. The station for this line was on Mount Vernon Street. In 2010, the center of the city districts and the newly established community Friends of the railway park began with estimates of the possibility of transforming the abandoned railway park into the exalted green park. The construction began in October 2016. In the first plan of planning it was planned to center a quarter of a mile off the stretch that stretches from Broad Street to Callowhill Street. This project includes a promenade, benches, a landscaped environment, a playground for children and the reinforcement of the existing 13th bridge. It is planned that the park will open at the earliest 2018

The objective of this project

The overground park will connect many city museums and galleries such as the Philadelphia Museum of Art, the Rodin Museum, the Barnes Foundation and the Community College of Philadelphia. Architects will retain authentic materials and visual simplicity of existing bridging construction. Pre-cast steel that will be smoked with wooden benches, platforms and fences. As far as vegetation is concerned, there will be grass, low-fruity shrubs, and trees that will shade. The project is named Rail Park, which could be a free-to-do translation of the Railway Park. As the metro was introduced, fewer people used overhead railways in some parts of the city reaches the height of the third floor. At the end of 1980, train traffic was completely suspended.

As a renewed public space, Viaduct will successfully bring together wealthy and culturally diverse communities, develop economically, and provide incentives for the development of this part of Northern Philadelphia. Similar projects can be found in Paris and New York. They contributed to the revival of part of the city and triggered economic development. For example, in New York, the reconstruction of High Line created suggestions for building more than 10 high-rise buildings on their way. As in Paris and New York, the new recreational comfort in this part of Philadelphia will result in additional economic investments and infrastructure development.
