First of all with passenger rail I will admit to a strong bias in favor of overnight conventional long distance trains with full dining cars. And of course these trains can also serve short distance passengers wanting to travel between any city pairs along the route.
So, what I'm wondering, if there are too many obstacles for this Texas Railway project to actually be developed could the focus return to, say, something like the former Chicago to Galveston Sana Fe Texas Chief (later the Amtrak Lone Star) that would be configured to serve Dallas (maybe including some suburbs and Denton) and serve passengers all along the route including Dallas to Houston commuters?
Now I know there's some hostility with Amtrak management and their board of directors toward the long distance service but after all, the original Amtrak mandate was to create a national inter-city system. So obviously Amtrak would need pressure from Congressional representatives and senators from Illinois, Missouri, Kansas, Oklahoma, and Texas to create a route like this.
Politically, could this approach be more feasible than that Texas Railway project? I do know that in 2018 Congressional pressure was brought to bear on getting Amtrak to back away from their terrible idea of breaking up the Southwest Chief route with a bus bridge from western Kansas to Albuquerque.
Oh - another bias of mine, because I live in Kansas, would be that a route like this would return Amtrak service to Wichita
