and the Fox Chase Line and alternate between terminating in Warminster and Fox Chase respectively. Most weekend trains are through routed with the Warminster Line and alternate between terminating in Glenside and Warminster. Stations The Airport Line makes the following station stops, after leaving the Center City Commuter Connection. History The line south of the Northeast Corridor was originally part of the Philadelphia, Wilmington and Baltimore Railroad main line, opened on January 17, 1838. The connection between the NEC and the original PW&B is made however by the later 60th Street Branch. A new alignment of the PW&B (now the NEC) opened November 18, 1872, and on July 1, 1873, the Philadelphia and Reading Railway, later the Reading Company, leased the old line for 999 years. Connection was made over the PRR's Junction Railroad and later the Baltimore and Ohio Railroad's Baltimore and Philadelphia Railroad. However, as a condition of the sale, no passenger service was provided. The line passed into Conrail in 1976 and SEPTA in 1983, with passenger service to the Philadelphia International Airport beginning on April 28, 1985. Infill stations were planned from the beginning of service, two of which were on the Airport Line proper: one at 70th Street, the other one at 84th Street. The latter station was opened in 1997 as Eastwick, while 70th Street was never built, and has since disappeared from maps. Additionally, University City station (proposed as "Civic Center", now Penn Medicine station) opened in April 1995 to serve all R1, R2 and R3 trains passing it. All these stations appeared on 1984 SEPTA informational maps, the first ones to show the Center City Commuter Connection and the Airport Line. SEPTA activated positive train control on the Airport Line on October 10, 2016. Ridership Between FY 2008-FY 2019 annual ridership on the Airport Line peaked at 2,457,743 during FY 2015, but fell to 1,518,250 by FY 2019.
