I was waiting for the F subway at 15th Street/Prospect Park Brooklyn this morning and a brand new train came in! Apparently they were testing it, it had the automated announcements and everything: To keep people from boarding, they were opening the doors on the wrong side. (More, including pictures)
This is a little old, but it's news to me. Apparently they've been testing these on occasion for a little while now. They have the automated announcements and light-up maps and the whole shebang. Anyone else seen these or have any more info?
