I would welcome this when I was traveling between LA & SF many years ago. I drove to Bakersfield to catch the Caltrain that takes me to Oakland. May not be a reason for many as the Caltrains weren't that packed.

They might be busier if they can take a high speed train directly between Bakersfield and LA, though.

If they succeed in getting it through the Tehachapi's, it will be a civil engineering feat without precedent in California history.

I am not holding my breath that it will come in 10 years, or even in my lifetime.
