Watch "Simply Railway" on YouTube - Texans are (slowly) starting to change their attitude towards public transport.
Easy answer - thanks to TexRail. And to Texas Central Railway.
TexRail uses the American equivalent of the class 231 being built for Trasport for Wales - the amazing and attractive Stadler FLIRT3 DEMU. They are so successful that another line in the Dallas metro area, the DART Silver Line, will also be run with Stadler FLIRT3 DEMUs. The FLIRTs (including one that is hydrogen!) will also run in California. Precisely the Arrow commuter rail between San Bernardino and Redlands located in Southern California, not far from Los Angeles. Then there is the double decker version, the KISS, which will also be used in California, but this time in the Bay Area (Caltrain from San Francisco to San Jose) in Northern California. And the KISS will be EMUs too, because the Caltrain is being electrified!
North America (USA & Canada) needs more of these beautiful and more attractive Stadler trains. European trains are so much better than these ugly silver American trains widespread all across the United States and Canada.
No offence to any Americans out there, but I do believe public transport is the only way to solve all the traffic congestions across the USA or Canada. Widening motorway (or interstates as Americans call) is not going to work in my opinion because it can damage buildings that surround them. And more airport gates isn't either because more flights means a higher chance of global warming.
As for Texas Central Railway. A new high speed line about to be built which will connect Houston with Dallas in just 1 hour 30 minutes / 90 minutes. They line will resemble a Japanese Shinkansen high speed line, and will use Shinkansen N700 series.
