What's wrong with this picture? No Houston.
That's right. Dallas will be the hub of the Texas high speed rail system, and Houston, apparently, won't be connected. Here's a little info about the recent High Speed Ground Transportation Conference in Milwaukee:

Among other surprises, Houston does not appear on the map of the proposed South Central High Speed Rail Corridor shown at the recent High Speed Ground Transportation Conference in Milwaukee. San Antonio, Austin, Dallas, and Fort Worth are linked, with continuing service to Tulsa and points north. Houston is tacked onto the tail end of the Southeast Corridor, with no connections west or in Texas. The 18th High Speed conference focused primarily on the upcoming national legislation, supported by both political parties, to pump $10 billion into high speed rail. The pressure on the nation’s airports is making short to medium haul rail service look much more attractive, particularly in places like the Northeast, Chicago, and Atlanta. The first generation of fast trains will operate at about 125 miles per hour, with incremental speed increases over time. On the horizon but drawing closer: “maglev”, or magnetic levitation, trains that ride four inches above the rails at very high speed. Japan reported that its maglev train, which will be deployed between Tokyo and Osaka, has reached speeds of 345 miles per hour and passed all its tests. China has begun construction of a German maglev system that will start between Shanghai and the Shanghai airport, a distance similar to the Houston-Bush trip, making the journey in 8 minutes. Eventually the line will link Shanghai with Beijing, a distance of about 750 miles. For more on high speed rail, http://www.fra.dot.gov/o/hsgt/hsgt.htm
