After construction, the station served as the PRR's sole Philadelphia stop for most long-distance east-west Main Line traffic to avoid a reverse move into Broad Street Station (and later 30th Street Station). It also served local trains from Fort Washington, Chestnut Hill, Bustleton, and Trenton, as well as a variety of services from the PRR-owned West Jersey and Seashore Railroad system. Within a decade of completion, the station was already overcrowded. On June 22, 1912, the PRR signed a million-dollar contract for massive renovations to the station. Designed by PRR architect William H. Cookman, the modifications reflected the latest in passenger station design.
