Confirming the information from NovaEngr, the Pacific Parlour cars are apparently gone, the first big casualty of the Anderson administration (aside from a LOT of senior, experienced managers who were either terminated or strongly encouraged to retire at year's end.) It is not just that the Pacific Parlour cars are going, but Amtrak is not replacing this service with other cars, the entire service is disappearing. For those who ride the Coast Starlight, this is a big thing. One of the reasons that people pay the big $$$ for sleeper accommodations on this train is because it has been the premier long-distance train... an example of what other trains should be.
Amtrak put out an earlier notice that the cars would return to daily service in March, this decision to eliminate the service apparently was a fast moving directive from top management and supersedes the earlier notice.
