You know Mark, that isn’t a wild idea. My dream basement, one of these days, would include a replica of a club car for the crew lounge. Having snacks from a real menu could be a great mid op session break.
LOve the slogan. One thing about the SUnday Brunch, is that brunch may not be enough to pay for dragging out a dedicated dining car. Instead, you might be bettter off, profitable for he RR using a full service business car or a plus service lounge that carries a small kitchen on-board, plus extra seating, and leave the Dining Car for Dinner and Black Tie. I may be wrong about that, but for the weight (fuel, mostly) vs passengers carried, brunch either may not be profitable, or else cost more than it’s worth. With a cafe lounge, or a business car (which your road would likely have in some form) you have more ticket earnings coming in to make the secondary diner a revenue car.
Or, maybe I’m trying to be too realistic
