I suppose the elimination of the tunnels made a significant dent in the capital cost, as well as the new alignment includes a good deal of single track (not a fan). I'm not entirely sure if the offset alignment would still be nearly all Caltrans land or if there was some private acquisitions involved with that, either way that's something that is avoided with the median running.

Brightline is saving BIG on grade separations. The I-15 freeway already has every road that it comes in contact with on bridge crossings or as an overpass already built in. Brightline has to build none of these, it's basically using what would be allotted for a future carpool lane, same with the Green Line and every other N. AMERICA median running train trying to build train on the cheap. DesertXpress was thinking like Europe, but our right of way planning is not set up for that and they would have been on the hook to build all new overpasses and crossing. Brightline is building this in the least expensive way possible.
Europe thinks differently about high speed/high capacity right of ways than we do. Most other HSR projects have their tracks parallel outside of the highway median because their mentality doesn't have them build highways past 3-4 lanes in each direction... Rarely will you see a 10 lane freeway in Europe... after 8 total lanes of congested roadway, their method for increasing traffic through an area is via rail expansion..., so rather than a road being the center of a right of way, they offset it to one side and they leave the other side for rail or other multi-use purposes. All we seem to think about and plan for in USA is ever expanding roads which is why a new interstate through a rural area will have 2 lanes in each direction and a few acres between the opposite driving lanes... all for future road growth.
Let’s say The USA and Eurasia have the same 14 spaces in a right of way... how it will be planned (diagram below). 7/8 are the center of the entire right of way. In Europe, 7/8 is planned for the end of the road and the beginning of other uses… In the USA 7/8 is planned to be the center of the road which in final widening stages becomes a carpool lane or high occupancy toll lane… oh…but I guess we can just throw a train in there if they make us.

California is building a high speed rail system from scratch as it doesn't have this prior allotment along the CA-99 corridor or anywhere. The USA will always have this problem until these priorities shift in how we plan for and use the available space we have. As rail advocates, one thing to advocate for if there is a freeway widening, would be that the entire road goes to one side of the right of way... you can keep it a secret that the other side could be used for rail and just say you are pro road way widening... but in the "right way." haha...
