If LGA were to wind up with XD40's, wouldn't it be hell for LGA's mechanics to having to maintain another bus model? Considering they already deal with MCI's, Gen II+'s, NG's and RTS's to begin with. And besides, where would they turn to when they need XD40 parts since pretty much every other XD40 depot are all Brooklyn Division (unless certain parts are cross-compatible from CP's C40LF's)...
I still have a feeling LGA may not get them..
