At about 240 miles this would be a great point to point run for HSR (200 + mph). No stops enroute. Multiple stops would be a better fit for rapid rail at 120 mph.
Such a point to point HSR train could be a starting point for a north/south HSR line that could be extended through Oklahoma, Kansas and Nebraska.
Think of the perishable or high value goods now transported by truck to and from Houston for export / import that could be on HSR to do the journey in less time, more affordably and with a smaller impact on the environment. Think of all the trucks you could pull off the road.
HSR needs to be looked at from a National perspective with each state planning to plug into a national grid of dedicated HSR tracks. Otherwise you are wasting your money on a fast train to no where. Like Acela.
