SEPTA AEM-7 No. 2301 prepares to depart Bethayres station in Huntingdon Valley, PA, along the West Trenton Line. The station to the far left was built in 1876 by the Reading Railroad and remains in service to this day. The AEM-7, on the other hand, is one of 7 rostered by SEPTA and is living on borrowed time, with its ACS-64 replacements about to enter service imminently.
