Is it planned to upgrade the connection from Rancho to LA? That's a horrible commute. About 35 miles with a travel time from 45- 120 regularly by car and ~90 minutes with current service.
There are no current plans to extend it to union station, but pretty much everyone agrees that it will happen shortly after construction finishes on the Vegas to Rancho Line, I would put it at around the mid 2030s
