From what I've read, the rebuilt Kawasaki's have Ds next to their car number, but I've seen two Kawasakis (760 and 768) with Ds next to them, but they do not appear to have been rebuilt (unless the LED signs were on the other side of the car). Or am I misreading it? According to the NETransit inventory, they haven't been rebuilt yet.
Also, what is the average time of a rebuild? Still looks like they're finishing up the remains of the first batch of cars.
Also, when a rebuilt car (according to the inventory page) is in testing, who is doing the testing? Alstom or the MBTA using a non-revenue train?
Thanks!
