I went by the Kawasaki plant yesterday and I saw 7255 & 7254 on the layup track. I don't know about the other 3 cars. Also, 7935 is sitting there, looking brand freakin' new. There's also some more trailer cars that are covered up.
That set saw service for literally 1-2 days before being taken out of service. It keeps having problems, which is making me wonder about the rest of the sets that will be converted.
