On the Broad Street Line, the trains have two chimes at the same tone "[dong-dong]" and a two-tone chime before any announcements. The Market-Frankford Line has automated announcements that go something like this: "This is a 69th Street train making all stops. This is a Frankford train making A stops. A stops only! [same for B] Doors opening! Doors closing!"
