Work begins on a $12B high-speed rail line between Las Vegas and Los Angeles

Original Article ↗ Hacker News Discussion ↗

Work is beginning on Brightline West, a $12B high‑speed rail line that aims to link Las Vegas with the Los Angeles region via Rancho Cucamonga, using mostly new track in the I‑15 median. Commenters debate whether the project will meaningfully compete with driving and flying given its 186 mph top speed, suburban LA terminus, and likely ticket prices, as well as the weak local transit networks at both ends. The project also sparks wider arguments about public vs. private ownership, U.S. cost overruns and NIMBY politics, and whether this line could serve as a proof‑of‑concept that finally makes large‑scale passenger rail viable in the United States.

Route, Termini & Connectivity

  • Line will run mostly in the I‑15 median between Las Vegas and Rancho Cucamonga (RC), not downtown LA.
  • Supporters say tying into Metrolink at RC then LA Union Station is “good enough” and avoids the hardest, most contentious urban segments.
  • Critics argue RC/Victorville “aren’t LA,” last‑mile transit is weak, and transfers plus local travel erase time savings vs driving or flying.
  • Some note existing Metrolink schedules are infrequent and end early; coordination and service upgrades are seen as necessary.
  • Vegas terminus is on/near the Strip, which is considered a strength compared to LA’s more remote terminus.

Speed, Travel Time & Ridership

  • Planned top speed ~186 mph; some call 125 mph “not real HSR,” others point out that 125+ mph meets common high‑speed definitions and average speed matters more.
  • Debate over competitiveness: door‑to‑door train time vs 4–5 hours driving vs ~1.5 hours flying plus airport overhead.
  • Many expect strong demand from leisure travelers (especially those drinking/using THC); others doubt middle‑class Angelenos will give up cars given LA/LV transit quality.

Costs, Funding & “Grift” Concerns

  • Project cost cited around $12B; half from federal grants and tax‑exempt bonds.
  • Some see this as classic “public risk, private reward” and expect overruns that trigger more subsidies.
  • Others counter that Brightline has actually delivered in Florida and that $ cost per km is not wildly out of line with European HSR.
  • Broader argument: rail should be publicly owned vs mixed models where private operators profit on public infrastructure.

Comparisons to CA High‑Speed Rail & Other Systems

  • Several commenters contrast this with California HSR’s Merced–Bakersfield “early operating segment,” which many deride as “nowhere to nowhere,” while others defend it as a learning/proving phase.
  • Repeated comparisons to European and Asian HSR: better city‑center stations, integrated metros, and differing population densities and politics.
  • Some hope Brightline proves HSR can be built on time/budget in the U.S.; others predict delay, scope downgrade, or cancellation.

Engineering & Alignment

  • Building in the freeway median is seen as simplifying land acquisition and environmental review.
  • Cajon Pass grade is flagged as a challenging segment that may limit sustained top speeds.
