Let me once again say that my comments are in no way confirming or denying the news that was posted at the top of this topic. I have no personal knowledge either way as to the validity of the statements made regarding the Crescent and the Sunset Limited and I caution all reading that this news is at present unconfirmed by any second source.
That said, I'm not sure why people are concerned about the Viewliner / Superliner thing. There is nothing that says that the route between NOL and SAN must use Superliner equipment. Amtrak has no contract with anyone that says Superliner equipment must run on this line. And if this were to happen, it would not be the first time in recent history that Amtrak has converted a train from Superliner equipment to Viewliner equipment. The Cardinal did just that about 4 years ago now, IIRC, might have been 3 years.
And if it does come down to a choice between no trains and Viewliner/Amfleet equipment running the route between NOL and SAN, then I suspect that most people would choose Viewliner/AMF equipment rather than no service. I know that I'd rather see Viewliner's and AMF II's between NOL and SAN, as opposed to no service.
