My wife and her grandfather took the train from Portland to Minnesota in the fall of last year. There were a number of issues with the service on the train that make it bad enough, but the speed of the train is a major problem of why these trains are somewhat worthless for travel. Freight trains get priority on the rail lines so many times the train was stopped for possibly hours waiting for freight trains to pass.
On my wife's trip the refrigeration went out at some point so cold food was no longer available, nor was food that required refrigeration before it was cooked. Fortunately they disembarked soon after that happened. The rest of the train was still a day or so from Chicago and those passengers were stuck with god knows what to eat.
