Yeah, they were still on the assembly line in California in the picture I posted above and have yet to be painted in the UTA livery:
The picture was from Daybreak's facebook page. (facebook.com/Daybreakutah)
We should be able to see them testing in Daybreak by the end of the month.
The new cars will have to run through the existing stations as at least the Mid-Jordan line will continue up the existing track to downtown. No modification is needed to make the existing platforms compatible, the current wheelchair ramps will just not be needed anymore.
