I wanted to love ekranoplanes, but although they have greater lift for a given span, they don’t have superior lift to drag ratios, which is what limits efficiency.

You could imagine a propulsion or even a lift mechanism closer to what is used for a hydrofoil. Modern sails or kites could improve the propulsion and handle the drag better.

I feel like we can make fast trains really worth it, but it makes the few connections I mentioned under-supported if you want to remain below a certain carbon footprint.
