Let's be real here: this isn't really Amtrak's fault, but rather that of Congress. Food and beverage service needs to break even by next year, which is causing these cuts. Why the LD trains are losing money is because of Amtrak's phony accounting, which nobody seems to ever bring up in the public space. This needs to be addressed immediately.
This is 2019, where the Court of Public Opinion deliberates online 24/7/365. When one has a bad experience, just about everyone and their mother turns to not just review sites like Yelp and Trip Advisor, but Twitter/FB/Instagram, where one bad review has a distinct possibility of going viral and being the next breaking news story on local at 6. Amtrak is shooting themselves in the foot here, but it may be a wound they're willing to take. I can see them in a year saying "See? LD trains are losing even more money now! Guess we gotta cut them!"
My view? The Silver Star experiment worked because the Silver Meteor was there as another option. Contemporary dining is going to fail miserably. Though I would ride an LD train in coach long before I would fly, when looking into future trips, I'm going to think twice (or three times) before committing to a possible sleeper because of the dining. It'll be interesting to see how the prices change, if they do at all.
Here's a data point for you: I was born in '98. I own a car but only because it's somewhat necessary where I live. I hate driving, not because of the traffic (which I don't see too much of), but due to cost (gas, parking, maintenance, gov't fees), safety, and environmental reasons. As soon as I graduate, I'm selling my car, leaving Connecticut for most likely a West Coast city, and working to save up some money with the U.S. economy before moving to Europe. My goal is to never own a car again and limit my usage of them as much as possible. Feel free to DM me for more info or to discuss further.
All I know is that every decision Anderson makes is very calculated. He knows exactly what he's doing.
