a few points points...
only 8 crossing of the trinity river exist between Dallas county and where the Trinity
becomes Lake Livingston. So IMO the closer to the Trinity the rail can run
the less useful land the government will have to "acquire".
How do you deer proof, cow proof, pig proof, egret proof, cormorant proof,
250 miles of track in East Texas??? Without making it completely elevated raising
the cost substantially???
Unless reliable, clean, safe public transportation exist to connect the stations
to the rest of the city it won't be used much making it a ANOTHER waste of
tax dollars.
The trains that I've used on my one trip to Europe have been running forever,
everyone that uses them have been using them their whole lives.
It's cultural
Once the trains are built it will literally take decades of subsidies
(making the initial investment look like couch money)
to keep them from going under until lifestyles adjust.
