High-Speed Rail Finally Coming to the U.S.

16. Květen 2024 v 15:11


In late April, the Miami-based rail company Brightline Trains broke ground on a project that the company promises will give the United States its first dedicated, high-speed passenger rail service. The 350-kilometer (218-mile) corridor, which the company calls Brightline West, will connect Las Vegas to the suburbs of Los Angeles. Brightline says it hopes to complete the project in time for the 2028 Summer Olympic Games, which will take place in Los Angeles.

Brightline has chosen Siemens American Pioneer 220 engines that will run at speeds averaging 165 kilometers per hour, with an advertised top speed of 320 km/h. That average speed still falls short of the Eurostar network connecting London, Paris, Brussels, and Amsterdam (300 km/h), Germany’s Intercity-Express 3 service (330 km/h), and the world’s fastest train service, China’s Beijing-to-Shanghai regional G trains (350 km/h).

There are currently only two rail lines in the U.S. that ever reach the 200 km/h mark, which is the unofficial minimum speed at which a train can be considered to be high-speed rail. Brightline, the company that is about to construct the L.A.-to-Las-Vegas Brightline West line, also operates a Miami-Orlando rail line that averages 111 km/h. The other is Amtrak’s Acela line between Boston and Washington, D.C.—and that line only qualifies as high-speed rail for just 80 km of its 735-km route. That’s a consequence of the rail status quo in the United States, in which slower freight trains typically have right of way on shared rail infrastructure.

As Vaclav Smil, professor emeritus at the University of Manitoba, noted in IEEE Spectrum in 2018, there has long been hope that the United States would catch up with Europe, China, and Japan, where high-speed regional rail travel has long been a regular fixture. “In a rational world, one that valued convenience, time, low energy intensity and low carbon conversions, the high-speed electric train would always be the first choice for [intercity travel],” Smil wrote at the time. And yet, in the United States, funding and regulatory approval for such projects have been in short supply.

Now, Brightline West, as well as a few preexisting rail projects that are at some stage of development, such as the California High-Speed Rail Network and the Texas Central Line, could be a bellwether for an attitude shift that could—belatedly—put trains closer to equal footing with cars and planes for travelers in the continental United States.

The U.S. government, like many national governments, has pledged to reduce greenhouse gas emissions. Because that generally requires decarbonizing transportation and improving energy efficiency, trains, which can run on electricity generated from fossil-fuel as well as non-fossil-fuel sources, are getting a big push. As Smil noted in 2018, trains use a fraction of a megajoule of energy per passenger-kilometer, while a lone driver in even one of the most efficient gasoline-powered cars will use orders of magnitude more energy per passenger-kilometer.

Brightline and Siemens did not respond to inquiries by Spectrum seeking to find out what innovations they plan to introduce that would make the L.A.-to-Las Vegas passenger line run faster or perhaps use less energy than its Asian and European counterparts. But Karen E. Philbrick, executive director of the Mineta Transportation Institute at San Jose State University, in California, says that’s beside the point. She notes that the United States, having focused on cars for the better part of the past century, already missed the period when major innovations were being made in high-speed rail. “What’s important about Brightline West and, say, the California High-speed Rail project, is not how innovative they are, but the fact that they’re happening at all. I am thrilled to see the U.S. catching up.”

Maybe Brightline or other groups seeking to get Americans off the roadways and onto railways will be able to seize the moment and create high-speed rail lines connecting other intraregional population centers in the United States. With enough of those pieces in place, it might someday be possible to ride the rails from California to New York in a single day, in the same way train passengers in China can get from Beijing to Shanghai between breakfast and lunch.

The Los Angeles Press Club on Thursday announced the finalists for the 66th Annual Southern California Journalism Awards, recognizing the best work in print, online, and broadcast media published in 2023.

Reason, which is headquartered in L.A., is a finalist for 14 awards.

A sincere thanks to the judges who read and watched our submissions, as well as to the Reason readers, subscribers, and supporters, without whom we would not be able to produce impactful journalism.

Senior Editor Elizabeth Nolan Brown is a finalist for best technology reporting across all media platforms—print, radio, podcast, TV, and online—for her November 2023 print piece, "Do Social Media Algorithms Polarize Us? Maybe Not," in which she challenged what has become the traditional wisdom around the root of online toxicity:

For years, politicians have been proposing new regulations based on simple technological "solutions" to issues that stem from much more complex phenomena. But making Meta change its algorithms or shifting what people see in their Twitter feeds can't overcome deeper issues in American politics—including parties animated more by hate and fear of the other side than ideas of their own. This new set of studies should serve as a reminder that expecting tech companies to somehow fix our dysfunctional political culture won't work.

Science Reporter Ronald Bailey is a finalist for best medical/health reporting in print or online for "Take Nutrition Studies With a Grain of Salt," also from the November 2023 issue, where he meticulously dissected why the epidemiology of food and drink is, well, "a mess":

This doesn't mean you can eat an entire pizza, a quart of ice cream, and six beers tonight without some negative health effects. (Sorry.) It means nutritional epidemiology is a very uncertain guide for how to live your life and it certainly isn't fit for setting public policy.

In short, take nutrition research with a grain of salt. And don't worry: Even though the World Health Organization (WHO) says "too much salt can kill you," the Daily Mail noted in 2021 that "it's not as bad for health as you think."

Managing Editor Jason Russell is a finalist in print/online sports commentary for his August/September 2023 cover story, "Get Your Politics Out of My Pickleball," which explored the emerging fault lines as the government gets involved in America's weirdest, fastest-growing sport:

Pickleball will always have haters—and if its growth continues, local governments will still face public pressure to build more courts. Some critics think the sport is a fad, but strong growth continues for the time being, even as the COVID-19 pandemic ends and other activities compete for time and attention. There's no need to force nonplayers to support it with their tax dollars, especially when entrepreneurs seem eager to provide courts. If pickleball does end up as an odd footnote in sporting history, ideally it won't be taxpayers who are on the hook for converting courts to new uses.

Reporter C.J. Ciaramella is a finalist in magazine investigative reporting for his October 2023 cover story, "'I Knew They Were Scumbags,'" a nauseating piece on federal prison guards who confessed to rape—and got away with it:

Berman's daughter, Carleane, was one of at least a dozen women who were abused by corrupt correctional officers at FCC Coleman, a federal prison complex in Florida. In December, a Senate investigation revealed that those correctional officers had admitted in sworn interviews with internal affairs investigators that they had repeatedly raped women under their control.

Yet thanks to a little known Supreme Court precedent and a culture of corrupt self-protection inside the prison system, none of those guards were ever prosecuted—precisely because of the manner in which they confessed.

Senior Editor Jacob Sullum is a finalist in magazine commentary for "Biden's 'Marijuana Reform' Leaves Prohibition Untouched," from the January 2023 issue, in which he disputed the notion that President Joe Biden has fundamentally changed America's response to cannabis:

By himself, Biden does not have the authority to resolve the untenable conflict between state and federal marijuana laws. But despite his avowed transformation from an anti-drug zealot into a criminal justice reformer, he has stubbornly opposed efforts to repeal federal pot prohibition.

That position is contrary to the preferences expressed by more than two-thirds of Americans, including four-fifths of Democrats and half of Republicans. The most Biden is willing to offer them is his rhetorical support for decriminalizing cannabis consumption—a policy that was on the cutting edge of marijuana reform in the 1970s.

Editor in Chief Katherine Mangu-Ward is a finalist for best magazine columnist for "Is Chaos the Natural State of Congress?" from the December 2023 issue, "Don't Just Hire 'Better Cops.' Punish the Bad Ones," from the April 2023 issue, and (a personal favorite) "Bodies Against the State," from the February 2023 issue:

Governments do unconscionable things every day; it is in their nature. But not all transgressions are equal. In the wake of the Iran team's silent anthem protest, an Iranian journalist asked U.S. men's soccer captain Tyler Adams how he could play for a country that discriminates against black people like him. What makes the U.S. different, he replied, is that "we're continuing to make progress every day."

The most perfect and enduring image of a person weaponizing his body against the state was taken after the brutal suppression of protests in Tiananmen Square in 1989. The unknown Chinese man standing in front of a tank didn't have to hold a sign for the entire world to know exactly what the problem was.

Reporter Christian Britschgi is a finalist for best long-form magazine feature on business/government for "The Town Without Zoning," from the August/September 2023 issue, in which he reported on the fight over whether Caroline, New York, should impose its first-ever zoning code:

Whatever the outcome, the zoning debate raging in Caroline is revealing. It shows how even in a small community without major enterprises or serious growth pressures, planners can't adequately capture and account for everything people might want to do with their land.

There's a gap between what zoners can do and what they imagine they can design. That knowledge problem hasn't stopped cities far larger and more complex than Caroline from trying to scientifically sort themselves with zoning. They've developed quite large and complex problems as a result.

Associate Editor Billy Binion (hi, it's me) is a finalist for best activism journalism online for the web feature "They Fell Behind on Their Property Taxes. So the Government Sold Their Homes—and Kept the Profits," which explored an underreported form of legalized larceny: governments across the U.S. seizing people's homes over modest tax debts, selling the properties, and keeping the surplus equity.

Geraldine Tyler is a 94-year-old woman spending the twilight of her life in retirement, as 94-year-olds typically do. But there isn't much that's typical about it.

Tyler has spent the last several years fighting the government from an assisted living facility after falling $2,300 behind on her property taxes. No one disputes that she owed a debt. What is in dispute is if the government acted constitutionally when, to collect that debt, it seized her home, sold it, and kept the profit.

If that sounds like robbery, it's because, in some sense, it is. But it's currently legal in at least 12 states across the country, so long as the government is doing the robbing.

Senior Producer Austin Bragg, Director of Special Projects Meredith Bragg, Producer John Carter, and freelancer extraordinaire Andrew Heaton are finalists for best humor/satire writing across all broadcast mediums—TV, film, radio, or podcast—for the hilarious "Everything is political: board games," which "exposes" how Republicans and Democrats interpret everyone's favorite games from their partisan perspectives. (Spoiler: Everyone's going to lose.)

The Bragg brothers are nominated again in that same category—best humor/satire writing—along with Remy for "Look What You Made Me Do (Taylor Swift Parody)," in which lawmakers find culprits for the recent uptick in thefts—the victims.

Deputy Managing Editor of Video and Podcasts Natalie Dowzicky and Video Editor Regan Taylor are finalists in best commentary/analysis of TV across all media platforms for "What really happened at Waco," which explored a Netflix documentary on how the seeds of political polarization that roil our culture today were planted at Waco.

Editor at Large Matt Welch, Producer Justin Zuckerman, Motion Graphic Designer Adani Samat, and freelancer Paul Detrick are finalists in best activism journalism across any broadcast media for "The monumental free speech case the media ignored," which made the case that the legal odyssey and criminal prosecutions associated with Backpage were a direct assault on the First Amendment—despite receiving scant national attention from journalists and free speech advocates.

Associate Editor Liz Wolfe, Senior Producer Zach Weissmueller, Video Editor Danielle Thompson, Video Art Director Isaac Reese, and Producer Justin Zuckerman are finalists in best solutions journalism in any broadcast media for "Why homelessness is worse in California than Texas," which investigated why homelessness is almost five times as bad in the Golden State—and what can be done about it.

Finally, Senior Producer Zach Weissmueller, Video Editor Danielle Thompson, Video Art Director Isaac Reese, and Audio Engineer Ian Keyser are finalists in best documentary short for "The Supreme Court case that could upend the Clean Water Act," which did a deep dive into a Supreme Court case concerning a small-town Idaho couple that challenged how the Environmental Protection Agency defines a "wetland"—and what that means for property rights.

Winners will be announced on Sunday, June 23 at the Millennium Biltmore Hotel in downtown Los Angeles. Subscribe to Reason here, watch our video journalism here, and find our podcasts here.

A technical paper titled “Electronic Noise Spectroscopy of Quasi-2D van der Waals Antiferromagnetic Semiconductors” was published by researchers at University of California Los Angeles.

Abstract:

“We investigated low-frequency current fluctuations, i.e. electronic noise, in FePS3 van der Waals, layered antiferromagnetic semiconductor. The noise measurements have been used as noise spectroscopy for advanced materials characterization of the charge carrier dynamics affected by spin ordering and trapping states. Owing to the high resistivity of the material, we conducted measurements on vertical device configuration. The measured noise spectra reveal pronounced Lorentzian peaks of two different origins. One peak is observed only near the Neel temperature and it is attributed to the corresponding magnetic phase transition. The second Lorentzian peak, visible in the entire measured temperature range, has the characteristics of the trap-assisted generation-recombination processes similar to those in conventional semiconductors but shows a clear effect of the spin order reconfiguration near the Neel temperature. The obtained results contribute to understanding the electron and spin dynamics in this type of antiferromagnetic semiconductors and demonstrate the potential of electronic noise spectroscopy for advanced materials characterization.”
