Since this is fantasy, what kind of amenities are you thinking? Dome cars on all trains that can use them? More Parlor Cars? More routes? Jacuzzis? I would be happy with mattress/bedding upgrades! Sometimes the food could be better and more choices too!
I'm talking about a step up from what qwe have now, so instead of adding new intermediate classes, I'm talking about things like better food, round-end obs cars, drawing rooms, maybe master rooms, dome cars, basically stuff like that.
I voted for higher price and more amenities. I would like to see first class lounge cars ala PPC added to all LD trains. I would like to see upgrades in the diners, ie return to china, glassware and more scratch prepared items. I dont know what percentage or dollar amount increase would cover those costs so I dont know how much higher the fares would be, but the ridership numbers are there. Amreica is returning to train travel. I'd gladly pay the price (and no I'm not a 1%er)
These stuff and some others are what I'm talking about.
In that case, the first things to do would be to upgrade linens and mattresses in the sleepers.
They should also return to real china and glassware, it actually 'more green' than using plastic and paper.
The same could be said for the meals-instead of prepackaged foods, return to cooked to order. Better menu, more regional and more selection.
Now for the expensive, therefore unlikely amenities/upgrades to be added:
I would love to see first class lounge cars on the LD Trains-like the PPC, but specific to each train.
Bring back Dome cars!
Addition of some type of 'slumbercoach class' in addition to the 'sleeper class'.
Reconfigure the bedrooms to allow for a larger bottom bed, add a small fridge. Stocked, of course.
The addition of a smoking lounge car, or a car at the end of the train that has a door you could open to a 'platform' or 'porch' to go outside and smoke. I know that's not the right words for it, but if you look at pics of old trains you'll get the idea. They used one for President Obama's train ride to the Inauguration.
Last, but not least, reinstate some of the old routes where there is no service. I can only speak to my area, but the two I would love to see reinstated would be the Pioneer and the Desert Wind. Both are north/south trains, which we don't have here since they are gone.
