Service to Reading Terminal ended on November 6, 1984 in anticipation of the opening of the Center City Commuter Connection, which opened on November 12, 1984. The tunnel, first proposed in the 1950s, is an underground connection between PRR and Reading lines; previously, PRR commuter trains terminated at Suburban Station and Reading at Reading Terminal. The connection converted Suburban Station into a through-station and rerouted Reading trains down a steep incline and into a tunnel that turns sharply west near the new Market East Station (now Jefferson Station). The conversion was meant to increase efficiency and reduce the number of tracks needed. On April 28, 1985, the Airport Line opened, providing service from Suburban Station via 30th Street Station to Philadelphia International Airport. This line runs along Amtrak's NEC, then crosses over onto Reading tracks that pass close to the airport. At the airport, a new bridge carries it over Interstate 95 and into the airport terminals between the baggage claim in arrivals and the check-in counters in departures. In 1990, R5 service was extended from Downingtown to Coatesville and Parkesburg. However, on November 10, 1996, R5 service to Parkesburg was truncated to Downingtown. In 2006, SEPTA started negotiations with Wawa Food Markets to purchase land in Wawa, Pennsylvania to build a new Park-and-Ride facility for a planned restoration of service between Elwyn and Wawa on the Media/Elwyn Line, which previously ran to West Chester.
