A decision has so far been made to send the train from LA to Palmdale en route to Bakersfield. That will require tunnels between Palmdale and Bakersfield.
Here is the map of the proposed system. As you can see on the map, it made too much sense to go direct from LA to Bakersfield.
Thanks for the map..it helps in comprehending just how they plan this thing. Not that I'll ever ride it as most of those places are off my list.
If I want to go, I'll drive!
