Here is my idea: Delete the Sunset limited and extend the daily Crescent to Houston (NYC to Houston daily). Rename the entire Chicago-San Antonio-Los Angeles route the Texas Eagle and operate it daily. The only leg missing would be Houston- San Antonio. I lived in Houston for many years and absolutely no one traveled between Houston- San Antonio using Amtrak because it took so long! Everyone either drove, flew, or boarded Greyhound. There is a huge amount of people traveling between the two cities. Therefore, if a truly high-speed train between Houston- San Antonio was developed, it would be highly successful in my opinion. Houston is the 4th largest city and it should be connected to NYC, Washington DC, and Atlanta via Amtrak and have high speed rail to San Antonio. With the high speed line between Houston and Dallas about to start, a high speed train to San Antonio probably is not a far-fetched idea!
