This again is another boondoggle and waste of money on the part of Texdot. Shreveport population = 218k, metro = 500k. Houston population = 2 million, metro almost 6 million. Texdot is dancing all around the real issue of Houston to Dallas rail service. First they wasted a bunch of money studying Houston to Austin with a meandering route through Hearne that would take 5-6 hours vs Greyounds 3 hours. The direct route was abandoned by the SP in the 1960's and Hwy 290 built on part of the ROW. Now this Shreveport thing. Strangely, SWA doesn't fly to Shreveport. lol. Greyhound runs at least 6 departures a day to Shreveport on a 3-4 hour schedule. American Airlines flys there several times a day. It's all just a smoke screen to hide from the real issue, and that is direct rail service between DFW and Houston on a four hour schedule. That would complete the so called 'Texas Triangle' of DFW/SAS/HOU/DFW. This is the basic route structure for passenger rail in Texas. Other destinations should be service by bus feeder lines, both highway and local metro. If we are to the point of starting up rail service between Dallas and Shreveport or adding the so called Crescent Star then the rest of the country must have the best rail service in the world. Before I did a 'Star' I would think about Texas to Colorado or bringing back the Lone Star or making the Sunset Limited daily or restoring SL service to Florida.
In an ideal world, the mid-west and southern states would have a corridor-style rail service between their major cities, connecting to the existing LD routes. Something like this-
Also, pigs would fly.
Until that happens, don't get your hopes high on any new corridors actually seeing the light of day in this part of the country.
I like the idea of a service Dallas-Little Rock-Memphis, and I see you've chosen the abandoned but still usable Rock Island line Little-Rock-Memphis, which has always been the most direct. I think if you are trying to have a corridor rather than express service Dallas-Houston though, you should have it serve Bryan-College Station since it is a pretty significant intermediate point, especially once you consider all of the student population there.
Don't read too much into the routes. I merely connected the cities using Google Maps so the routes you see are actually roads, not railroad tracks!
About College Station, yes, I would also love to see that being included in the scheme of things if and when Texas gets serious about inter-city corridor rail, but the location of that town is such that I have yet not been able to figure out what would be the best way to connect it- on Dallas-San Antonio leg, San Antonio-Houston leg or Houston-Dallas leg.. one of the sections will need to take a significant detour from the shortest path, the question is, which one would make most sense, or rather, least negative impact on the popularity of the train among city to city travelers.
