The TTC is a 50 year project. Why do we need commuter rail to Killeen? I'm sure people 50 years ago would have asked similar questions about the necessity of 4 lane highways crossing the nation. It's called "vision". A lot of folks don't have much of it.
Killeen does not need a commuter rail. Neither does Tyler, or Brownsville, or Midland, or Waco.
Build highways to nowhere and light rail in cities that have no need for them? That's Perry's "vision" for Texas.
However, if it keeps the residents of those areas in, I am all for it. However, I certainly is totally mystificated as to how this is supposed to hook up with other states. (Even if they are unrecognized by Texans.) Do we all get these super-duper Spanish Corridors? Will it allow our 100 Million + new residents a way to get back to Chihuahua to see the folks? Will the tires on Mexican 18-wheelers have tread?
And can I have taco concession at the truck stops?
