The first ACS-64 unit is now in service for Southeastern Pennsylvania Transportation Authority (SEPTA)/SEPTA - iseptaphilly.com! At about 1017 on Wednesday, July 11, 2018, Siemens ACS-64 901 broke the banner and entered the Chestnut Hill East Station. The riding public, SEPTA transportation management, elected officials, media were on hand for the banner breaking! Congratulations to all who worked so hard to make this happen and improve public transportation.
