7 cars are in active revenue service right now, and as I type this 3910 is testing outbound on the D at Newton Centre per the train tracker.So what happened to the Type 9 Green Line trains? I haven't a single one since a sighting in late Spring early Summer?
3911 was the latest new delivery last week. I don't know if they've appeared anywhere other than the D yet. They've been testing on the C all month, but no confirmation of any passenger runs there yet.
