For Sunset/Eagle passengers to/from Houston and New Orleans, I'm more concerned about the low average speed, 40 or 45 mph iirc.
Houston-San Antonio should be a state-supported corridor ..
...
If you want to do the state corridor way, I'd go with DAL-SAS as a state corridor option first as my plans dictate. ... Clearly the only SAS-HOU option now is the current SL with lousy times into/out of SAS so multiple frequencies should surely increase ridership between those cities. But as long as the SL leaves SAS in the graveyard shift (and arrives in LAX before 6am) that IMHO is still a problem.
I wasn't thinking priorities there.
But here:
I'd warn that Laredo-San Antonio-Austin-Ft Worth is the NAFTA rail route for freight (as is I-35 for trucks) from/to Mexican factories. It's terribly crowded and likely to get more so.
Some years down the road, commuter rail San Antonio-New Braunfels-San Marcos-Austin-Round Rock-Georgetown-Taylor could help with better tracks, but only on that segment. The northern half to Dallas-Ft Worth would remain crowded and slow.
San Antonio-Houston is busy for freight, but nothing like the NAFTA route.
Surprisingly, sprawl hasn't yet ruined the land between exurban San Antone and exurban H'town. (They're working on it, tho. LOL.) The right of way is wide enuff for many long sidings or double track. Many level crossings need upgrades in any case, but there's usually room to do grade separations. So this a good segment to spend money and get quick results. North from San Antonio, where the tracks run thru towns no longer small, will be much more costly per mile, much more. (We're talking my childhood stomping grounds, btw.)
East from H'town you could get a commuter/short-corridor line to Beaumont, an old oil industry city with strong ties to Houston. Then to make things really work to N'awlins, you'd need cooperation from Louisiana. Two states with lots of haters. Still, a large construction project always presents large opportunities for graft and contractor corruption, so it could appeal to many powerful people in Austin and Baton Rouge.
Another way to upgrade the
Eagle is Marshall-Longview-Mineola (for Tyler)-Dallas-Ft Worth. Fairly dense intermediate population is left over from the great boom of the giant East Texas Oil Field. Push the route from Marshall barely 40 miles to Shreveport, where riverboat gambling is a huge draw from the D-FW MetroPlex, so it overlaps the
Eagle almost all the way. Money spent on upgrades would benefit both.
The SB
Eagle leaves Marshall at 7:50 a.m. to arrive Dallas at 11:30. NB it leave Dallas at 3:40 p.m. to arrive in Marshall at 7:30 in the evening. Not bad, but doesn't get the gamblers to Shreveport. (There is a kinda sorta, but slow, Thruway bus.) Taking an hour, even hlf an hour, out of the run times would be great.
If Shreveport puts in for operating support, and Dallas joins in, and those intermediate towns start to whine, "Texas is helping to support a train to Oklahoma City, why not help with
our train?" some Texas money might be forthcoming for one or two corridor trains each way.
But that segment Marshall-Ft Dallas is 151 miles, in 3 hrs 40 minutes or 3 hrs 50 minutes, plus about an hour on the bus to the casinos. Too slow a trip, at barely 40 mph.
So, one TIGER grant at a time (or how?), speed up that segment for passenger trains, to get Dallas-Shreveport under 4 hours, and make room for another 2 or 3 corridor trains on this route. Getting the
Eagle into Dallas at 11 a.m. instead of 11:30 would be a good thing, too.
Another way to crack the nut. If Amtrak ever gets money for new routes (like, after a nuclear temper tantrum in the Middle East, or whatever) : Take a second run of the
Crescent, (the long-desired
day train?) or split the
Crescent we've got at Atlanta (or Birmingham if ATL never gets it act together), then Meridian-Jackson-Vicksburg-Monroe-
Shreveport-Dallas-Ft Worth (or even on down to San Antonio, I'm open to that). That creates a second frequency for the gamblers and others on the East Texas Corridor.
Then take Bobbi Jindal's suggestion, before they told him that because Obama was for trains all right-thinking people were supposed to be against them. Jindal wanted New Orleans-Baton Rouge-Alexandria-
Shreveport-Dallas-Ft Worth. (You could, I guess, make that one another version splitting off the Crescent Birmingham-Montgomery-Mobile-Biloxi-New Orleans-Baton Rouge-
Shreveport-Dallas-Ft Worth, if you could do another long distance train.) So that gets another frequency for the gamblers and others on the East Texas Corridor.
Both of those schemes add a lot of connectivity, and with the
Sunset Shuttle, they cover all of Louisiana, to offset the political power of the haters.
But as for priorities, they all look good. So I'll let the Lege in Austin (and the CongressCritters in D.C.) sort them out.
