Virgin Trains is building a high speed rail link between !SoCal and #Las_Vegas, #NV. They plan to end it North of the Cajon Pass. That may be because of problems acquiring rights-of-way there.
I just think that not extending the line to Ontario International Airport (ONT) in Ontario, #CA, is likely to doom the train to low ridership. If I'm driving from #Los_Angeles, by the time I get to the Mojave Desert, I've already spent half of the time it takes to get to Las Vegas. Am I then going to pull into the park and ride and hop on the train? I just do not think most people will do so.
The extra hour of drive time is probably the difference between driving or hopping on a train.
NOTE: I'm in favor of the high speed rail link. I just think they need to extend it, so that the SW terminus is closer to most of the people who'll ride it.
If you live in #Las_Vegas, but work in Los Angeles, either you spend more time getting to and from work than you spend at home, or you'll get a small place somewhere much closer, so you can stay during the week and just go home on weekends. Either way, you should include those costs in your affordability figures, because you may find that you didn't really save money versus living in #Los_Angeles County. (I used a #SoCal example, but you can switch to other areas and see the same situation.)
