Title:
Philadelphia

Context:
In 1981, large sections of the SEPTA Regional Rail service to the far suburbs of Philadelphia were discontinued due to lack of funding. Several projects have been proposed to extend rail service back to these areas, but lack of funding has again been the chief obstacle to implementation. These projects include the proposed Schuylkill Valley Metro to Wyomissing, PA, and extension of the Media/Elwyn line back to Wawa, PA. SEPTA's Airport Regional Rail Line Regional Rail offers direct service to the Philadelphia International Airport.

Question:
Has service ever been restored?
