The San Bernardino Railroad Historical Society ran ATSF steam and 2 Amtrak units with PV out of LAX this AM to Parker, Az. Some good videos posted at LINK.
Yes- that consist was parked at LAUS during NTD. Got a chance to tour it- a very nice train. I would have loved to get on it, but alas, that could not happen. Got some nice pictures, too...
