High-Speed Las Vegas Train Back On Track As U.S. Reviews L.A. Extension

I'm less concerned that this project won't get built and more concerned it won't get built correctly. The original Desertxpress FEIS was very promising in its specs and I'm leery this project under Brightline will cut every possible corner until it barely resembles acceptable HSR practice. I do hope I am wrong.

Well, I think the key parts are in place. It will be a sealed corridor with no grade crossings running nonstop from Victorville to Vegas (with possible extension to Rancho as shown in the rendering). That alone should allow 125mph operation, which is still fairly quick if they can sustain that speed. Comparable to Germany's ICE, if not the TGV or Chinese lines. Over time I assume any slow sections can be upgraded.

It's official!! Breaking ground on Boca Raton station.

Edens says Brightline high-speed rail project is ‘at the 1-yard-line’
By Mick Akers Las Vegas Review-Journal January 24, 2022 "Could 2022 finally be the year construction on the long-discussed high-speed train between Las Vegas and Southern California gets underway? Wes Edens, co-CEO of Fortress Investment Group, which owns the high-speed passenger rail line Brightline through an affiliate, thinks so. Edens said he expects to break ground on the project by the end of the year. This claim has been made before, but with plans to extend the rail line into Los Angeles now in place and the approval process moving forward, Edens said this time is for real..." https://www.reviewjournal.com/news/n...-line-2518090/ |

The fact of the matter is we don't exactly know what is really being planned. The media reports continue to say things like 180mph but we know that Brightline applied to amend the original FEIS and detailed corridor plans with the FRA and agreements with Caltrans to increase the amount of median running. As you mentioned, the addition of median running will reduce curve radii which will lower operating speed. The shift in alignment also includes reducing the amount of cuts and ahort tunnel segments which I believe equats to an "over the top" at grade alignment at even steeper grades than were originally planned for under Desertxpress. This will also likely force a slower top speed.

Clearly the solution to Brightline in Florida is for Floridians to just get used to living around trains.
In the Southwest, it looks like most of the curves on I-15 could support high speed operation with a tilting trainset and a high superelevation (not sure exactly how fast, but that technology has come a long way). They can't do this kind of thing on any line with significant freight traffic, but certainly can on passenger-only lines where the track geometry can be optimized for speed and not its ability to carry heavy loads. Nobody else in the world would build a greenfield rail line with curves so tight as to require tilting trains, but (sigh) the US is different. It may be that the environmental mitigations required to leave the I-15 corridor are so expensive as to force this kind of compromise. |
Im curious if Caltrans will agree to broadening the curve of some directional lanes to allow the broadening of curves on the railway at certain turns in the corridor where there is center running. By definition it only requires one side of the divided highway to be modified.

Heads up!!
Second BrightBlue just left from Sacramento factory. It's on the way to Florida now. Get a camera ready!! :tup: |

Unfortunately, another person was struck and killed by a Brightline train yesterday.

I hate to sound insensitive but Florida seems to be giving India a run for its money.

I don't think it's about Brightline minimizing costs - building a rail line in a highway median isn't cheap, due to limited access, limited room for staging and constant work for Maintenance-of-Traffic. But maybe the savings on earthmoving/regrading from using the median outweigh the added complexity of building between 4 lanes of 80mph traffic. |
I know it's too easy, but what environment??? My god it's a freaking moonscape.
