they are California owned not amtrak, they are incredibly slow to board. of the 14 we are luck to have about 10 in service at any time.The should send the ComArrows up to Seattle, and send as many Horizons back to Chicago, which needs more equipment, and possibly send some of their Amfleet back to the east coast.
CA may keep them in service as a stop gap solution along the coast until new equipment can arrive but that requires CA to actually want to run service along the coast which so far has just been study after study for 35 years now.
