Not sure what you meant by "We here are anomalies." but there are no anomalies that I can see. They just jacked up the prices.
We the fanatical daily mind-wanderers of preferring to be on a train are anomalies compared to the rest of the folks that ride Amtrak - to get from point A to point B. We are the ones ecstatic to get a better price AND to spend an extra day on the train. From revenue management, though, getting the most money getting people from point A to B as quickly as possible has the best potential for return.
I would not be so quick to lump us all in to that definition. I use Amtrak for transportation because I prefer it to other forms. I highly suspect MOST people on Amtrak trains feel the same way. Not that I think it is crazy, but I have never taken a train vacation. We just use the train on our vacation (and consider it part of the vacation).
Anyway, I am not sure what that has to do with the huge price increase on the SWC, other than them wanting to get the most they can get. Problem is, I think this will hurt the train. I have used it for the past 5 years for our yearly vacation. However, next year, I have already made other plans. Amtrak has successfully priced me, a dedicated train traveler, out of using the SWC.
Lets hope they come to their senses soon and change the pricing. If they do not, you will not see sold out SWC trains very often next year.
