SEPTA's AEM-7's, No. 2302, leads the last of three evening push-pull commuter express sets into Overbrook station in the western suburbs of Philadelphia. SEPTA staggers their express trains, each stopping at a specific set of stations while bypassing others already served or to be served. This last set serves the stations closest to downtown Philadelphia. Arriving on the outside "local" track, a clear view of the still in service tower is afforded, as is the former Pennsylvania Railroad 1858 bulit station, also still in service. The bridge above carries City Line Avenue, also known as US Route 1.
