<b>Final Shove.</b> Southeastern Pennsylvania Transportation Authority (SEPTA) 2304 (AEM-7, EMD, 1987) was holding the markers on "Work Extra 52" as it passed Morris in Morrisville, Pennsylvania on Saturday, May 14, 2022. All 8 of SEPTA's AEM-7/ALP-44M commuter electric motors were removed from revenue service in 2018 and have only made occasional appearances in work service, mostly on leaf wash train in the autumn.
