Experts weigh in on health, environmental and regulatory concerns following Ohio train derailment
The 2023 Ohio train derailment (also called the East Palestine train derailment) occurred on February 3, 2023, at 8:55 p.m. EST (UTC−5), when 38 cars of a Norfolk Southern freight train carrying hazardous materials derailed in East Palestine, Ohio, United States. Several railcars burned for more than two days, and then emergency crews conducted a controlled burn of several railcars at the request of state officials, which released hydrogen chloride and phosgene into the air. As a result, residents within a 1-mile (1.6-kilometer) radius were evacuated, and an emergency response was initiated from agencies in Ohio, Pennsylvania, and West Virginia. (wikipedia)
West Virginia University experts in fields ranging from law to health to water quality can provide insights into potential community effects near the East Palestine, Ohio, site of the Feb. 3 train derailment and subsequent chemical fire.
“The most pressing issue is the lack of transparency and lack of information sharing. Citizens in East Palestine and surrounding communities are understandably concerned about whether the air is safe to breathe and the water is safe to drink. EPA Administrator Michael Regan told residents to ‘trust the government.’ That’s not enough. The residents need data and facts. Norfolk Southern and the state and federal governments need to be more forthcoming.
“Related to this, the United States initially failed to deploy the Federal Emergency Management Agency to the area, saying the agency doesn’t respond to these types of emergencies. The federal government has since changed its mind and is deploying FEMA, but a rapid deployment would have reassured residents that they have some help.
“The federal government has given notice to Norfolk Southern under the Comprehensive Environmental Response, Compensation and Liability Act that the government intends to hold the company responsible for the cleanup of the spill. In addition, federal and state laws set out emergency response protocols.
“Stricter regulations that were considered in the past for speed limits, stronger rail cars, better brakes and more transparency to state and local officials are being reconsidered now. Some of the cars on the train that derailed were better able to withstand the crash without rupturing, but not all of the cars had been updated. Regulations expanding the scope of hazardous materials subject to heightened regulation during transport were also rejected in the past.” — Jesse Richardson, professor of law, lead land use attorney, WVU College of Law
“At this time, it is difficult to assess the scope of the impact this will ultimately have (near the crash site). Chemicals were spilled, and a potent mixture of toxicants were aerosolized on a massive, uncontained scale. Acute toxicities have been observed in wildlife and humans, but the situation has changed in the past couple of weeks. It may no longer be possible to identify what caused these acute effects. However, the environment and greater ecosystem must be robustly monitored if future adverse health effects are to be avoided.“Incomplete combustion of vinyl chloride resulted in the creation of a complex mixture of toxicants. In general, this aerosol was a mixture of a gases and solid particles that, when considered together, is capable of a larger area of effect on the ecosystem. Further, when inhaled, mixtures of this type are capable of penetrating into the deep lung and causing more harm.” — Timothy Nurkiewicz, professor and chair, Department of Physiology, Pharmacology & Toxicology, WVU School of Medicine
“Soil retains the chemicals that spilled. Those chemicals are volatile, and the soil can become a ‘sink’ from which entrained, spilled chemicals could volatilize, becoming resuspended in the air — thus the concern and the potential need for quickly removing that soil as a source.” — Michael McCawley, clinical associate professor, Department of Occupational and Environmental Health Sciences, WVU School of Public Health
“Soils and hillslopes play a critical role in generating streamflow. When rain hits the ground or when snow melts, water flows through soils and overland more easily. The wetter soils are, the more connected seemingly disconnected locations are on the landscape to streams and rivers. One of the consequences of a warming atmosphere is more frequent and intense rain, something we all are aware of from our lived experiences. With more rain, soils are wetter, especially the clay soils that dominate our region, and especially during winter when most of our trees are dormant and not returning water back to the atmosphere through transpiration. As a result, there is greater potential for contaminants that are released on to the land surface to be dispersed downslope and downstream. Furthermore, once contaminants are below the surface, groundwater further disperses pollution, increasing the challenges of containment and clean up. So indirectly, climate change is increasing the complexity of the problem. This is especially true since most of policies, practices and rules that are designed to protect people and the environment are based on last century’s rainfall. Society, as a whole, is woefully underprepared to address disasters like the derailment in East Palestine.
“To the best of my knowledge, the prevailing winds are blowing away from West Virginia, but the Ohio River does ‘touch’ West Virginia as it forms part of our western boundary. As water flows downstream, it will mix with water stored in the alluvial aquifers along the banks of the Ohio River. Some communities and industries along the Ohio River use water that is pumped from these alluvial aquifers that could become contaminated by the vinyl chloride soiled in East Palestine. The cases of misinformation around the derailment highlights the importance of citizens becoming knowledgeable about how the world in which they live works. A great resource to learn how East Palestine is hydrologically connected to communities downstream can be found here – https://river-runner.samlearner.com/. — Nicolas Zegre, associate professor of forest hydrology, WVU Davis College of Agriculture, Natural Resources and Design
“The derailment occurred in East Palestine, Ohio, and there are several creeks in the area that drain to the Ohio River. They are about 16 miles from the river. About half of any vinyl chloride entering the creek leading to the Ohio River would be volatilized every two hours. The distance from East Palestine to the river is about six miles. Assume the stream is flowing at about 22 minutes per mile and the maximum concentration of vinyl chloride in water is about 2.7 mg/L. So, whatever the starting concentration, it would be reduced by about 87% over the 16-mile distance to the river. Whatever reaches the river would be diluted by the 35,500 cubic feet per second of river flow on Feb. 3, 2023.
“There was a map showing the Ohio River watershed with the implication that all tributary streams within the watershed would be contaminated. That’s incorrect since water flows downhill from the outer reaches of the watershed to the Ohio River, not the other way. So, the only waters that could possibly be affected would be the creek leading to the river from the derailment site and the river itself. There are dams along the river and they maintain a pool elevation for navigational purposes. As a result, the pool levels would determine the maximum level that Ohio River water could reach.” — Paul Ziemkiewicz, director, West Virginia Water Research Institute at WVU

Was there a time it was considered that “The City of Angeles,” had reached “Peak Car?”
I recently came across an article posted by the Metro Digital Resources Librarian on the Dorothy Peyton Gray Transportation Library and Archive web site run by Metro Los Angeles. The article talked about LA’s new obsession with the automobile and how it gained popularity, in the early 1920s.
Peak Car Era
Library researchers pointed out that notable resources concurred with this, including Scott L. Bottles’ Los Angeles and the Automobile: The Making of the Modern City, and Ashleigh Brilliant’s The Great Car Craze, How Southern California Collided with the Automobile in the 1920s.
The automobile was new and fresh, and also offered freedom to its owners, who realized that they could become more mobile and not rely solely on the massive LA street car network at the time. The number of vehicle registrations in Los Angeles had quadrupled in just an eight-year period from 1914-1922.
“Automobile use exploded as the passenger vehicle transitioned from a hobbyist’s pursuit to a relatively affordable means of getting around the sprawling region and beyond.”
Metro Librarian found out what was happening on the public transit side of the story when they found an article published in Electric Railway Journal titled “California and Her Tractions, Part II.“
MetroDigital Resource Librarian:
As one of several features titled “A Series of Articles on Salient Phases of the Electric Railway Situation,” author Edward Hungerford details the then current state of public transit in the Los Angeles area.
And within that overview, he interviews Paul Shoup, Pacific Electric Railways president and vice-president of Southern Pacific Company.
Hungerford documents Pacific Electric’s earnings in a recent six-month period, and asks Shoup “for the real translation of these figures.”
Shoup responds by stating:
“They mean that the peak of the competition of the automobile, publicly or privately owned or operated, has been reached out here — and passed. Not only is the rapidly rising cost of cars and tires and gasoline and oil beginning to deter the overenthusiastic motorists, but I think that the novelty of excessive motor riding also is rather wearing off. The hazards of driving on crowded highways are becoming more apparent and parking spaces in towns and cities more a question of doubt.
In addition to our great numbers of motor stage routes in every direction, we now have some 500,000 automobiles in California licensed for pleasure purposes, to which should be added the cars owned and operated by the 100,000 Easterners who come out here every winter. The competitive effect of all these cars has been, and still is, vast indeed. But we already can see in it a declining curve.“
Yes, you read that right, Shoup declared that personal vehicle usage had peaked and that it was on the decline.
Shoup explains that Los Angeles Railway profits were consistent with those of Pacific Electric, but acknowledges that “increases in both operating cost and taxes had gone ahead a little more than proportionately.” But he intimates that the rising cost of automobile operation (gas, tires) means that cars will cease their encroachment into transit’s share of mobility.
MetroDigital Resource Librarian:
This statement was part of an interview published in a national journal. Was he telling industry professionals what they wanted to hear? Did he want to assuage fears of rail employees that their jobs were going to disappear as more people purchased and used automobiles? Was he hoping that his perspective would turn into a self-fulfilling prophecy so he could remain atop Pacific Electric and Southern Pacific?

Brightline West Project
As a passionate advocate for modern transportation, I am beyond excited about the latest development in American rail: the Brightline West project, which is officially one step closer to reality with the recent signing of a $3 billion grant agreement by the Federal Railroad Administration (FRA)! This project isn’t just another rail line; it’s a historic leap forward for high-speed rail in the U.S. and a beacon of progress for public transportation enthusiasts like myself.
On September 26, 2024, this monumental agreement was finalized, marking the beginning of what many of us have dreamed about for decades—true high-speed rail connecting Las Vegas to Southern California! With trains capable of reaching speeds over 200 miles per hour, we’re talking about radically transforming how we travel between these two bustling regions.
To have a project of this magnitude come to life thanks to a strong public-private partnership is inspiring. Just look at the numbers: over 35,000 jobs are expected to be created, including 10,000 union construction jobs. This is a huge win, not only for those in the industry but also for local economies and communities, and it sets a precedent for future infrastructure efforts across the country.
Michael Reininger, the CEO of Brightline, really hit the nail on the head with his assertion that this project will “jumpstart the high-speed rail industry in America.” It’s long overdue, and finally, we are moving forward. The Brightline West project won’t just connect cities; it will embody a bold, eco-friendly approach to our transportation challenges—reducing CO2 emissions by over 400,000 tons annually and removing three million cars off the roads that currently choke the I-15.
Imagine this: a seamless, comfortable two-hour journey from Las Vegas to Rancho Cucamonga, complete with onboard amenities like food and Wi-Fi. For someone who routinely endures the endless traffic jams on the freeway, the thought of relaxing in a sleek train while taking in the stunning California desert views excites me beyond measure! No more cramped airplane seats or endless hours stuck in a car; we’ll be able to travel in style and comfort.
And it warms my heart to see the emphasis on sustainability and environmental responsibility. The fact that Brightline West will utilize zero-emission, fully electric trains positions it as the premiere green transportation choice in America. It’s initiatives like these that give me hope for our future and showcase how modern rail can lead the way in combating climate change.
Heavy construction is slated to kick off in 2025, and early groundwork is already ongoing. Crews are busy drilling geotechnical borings along the I-15, and I can practically feel the anticipation in the air! Soon enough, we’ll see new stations sprouting up, including one right in the heart of Las Vegas—a city known for its bright lights and bustling energy!
As someone who often travels for both leisure and business, I am particularly looking forward to the role this project will play as we approach the 2028 Olympic Games in Los Angeles. Brightline West will undoubtedly serve as an essential transport option for visitors and residents alike, highlighting what a modern transportation system can achieve.
In closing, there’s so much to be excited about! The Brightline West project calls forth a vision of the future that is connected, rapid, and environmentally conscious. It represents the culmination of years of advocacy, dreaming, and hard work. I look forward to seeing how this journey unfolds as we ride the rails toward a new era in American transportation.
Here’s to the future of rail in America! 🚄🌟
Until next time, happy rail journeys, everyone!

Tech
A third of the world’s population lacks internet connectivity − airborne communications stations could change that
Mohamed-Slim Alouini, King Abdullah University of Science and Technology and Mariette DiChristina, Boston University
About one-third of the global population, around 3 billion people, don’t have access to the internet or have poor connections because of infrastructure limitations, economic disparities and geographic isolation.
Today’s satellites and ground-based networks leave communications gaps where, because of geography, setting up traditional ground-based communications equipment would be too expensive.
High-altitude platform stations – telecommunications equipment positioned high in the air, on uncrewed balloons, airships, gliders and airplanes – could increase social and economic equality by filling internet connectivity gaps in ground and satellite coverage. This could allow more people to participate fully in the digital age.
One of us, Mohamed-Slim Alouini, is an electrical engineer who contributed to an experiment that showed it is possible to provide high data rates and ubiquitous 5G coverage from the stratosphere. The stratosphere is the second lowest layer of the atmosphere, ranging from 4 to 30 miles above the Earth. Commercial planes usually fly in the lower part of the stratosphere. The experiment measured signals between platform stations and users on the ground in three scenarios: a person staying in one place, a person driving a car and a person operating a boat.
My colleagues measured how strong the signal is in relation to interference and background noise levels. This is one of the measures of network reliability. The results showed that the platform stations can support high-data-rate applications such as streaming 4K resolution videos and can cover 15 to 20 times the area of standard terrestrial towers.
Early attempts by Facebook and Google to commercially deploy platform stations were unsuccessful. But recent investments, technological improvements and interest from traditional aviation companies and specialized aerospace startups may change the equation.
The goal is global connectivity, a cause that brought the platform stations idea recognition in the World Economic Forum’s 2024 Top 10 Emerging Technologies report. The international industry initiative HAPS Alliance, which includes academic partners, is also pushing toward that goal.
Fast, cost effective, flexible
Platform stations would be faster, more cost effective and more flexible than satellite-based systems.
Because they keep communications equipment closer to Earth than satellites, the stations could offer stronger, higher-capacity signals. This would enable real-time communications speedy enough to communicate with standard smartphones, high-resolution capabilities for imaging tasks and greater sensitivity for sensing applications. They transmit data via free-space optics, or light beams, and large-scale antenna array systems, which can send large amounts of data quickly.
Satellites can be vulnerable to eavesdropping or jamming when their orbits bring them over adversarial countries. But platform stations remain within the airspace of a single country, which reduces that risk.
High-altitude platform stations are also easier to put in place than satellites, which have high launch and maintenance costs. And the regulatory requirements and compliance procedures required to secure spots in the stratosphere are likely to be simpler than the complex international laws governing satellite orbits. Platform stations are also easier to upgrade, so improvements could be deployed more quickly.
Platform stations are also potentially less polluting than satellite mega-constellations because satellites burn up upon reentry and can release harmful metals into the atmosphere, while platform stations can be powered by clean energy sources such as solar and green hydrogen.
The key challenges to practical platform stations are increasing the amount of time they can stay aloft to months at a time, boosting green onboard power and improving reliability – especially during automated takeoff and landing through the lower turbulent layers of the atmosphere.
Beyond satellites
Platform stations could play a critical role in emergency and humanitarian situations by supporting relief efforts when ground-based networks are damaged or inoperative.
The stations could also connect Internet of Things (IoT) devices and sensors in remote settings to better monitor the environment and manage resources.
In agriculture, the stations could use imaging and sensing technologies to help farmers monitor crop health, soil conditions and water resources.
Their capability for high-resolution imaging could also support navigation and mapping activities crucial for cartography, urban planning and disaster response.
The stations could also do double duty by carrying instruments for atmospheric monitoring, climate studies and remote sensing of Earth’s surface features, vegetation and oceans.
From balloons to airplanes
Platform stations could be based on different types of aircraft.
Balloons offer stable, long-duration operation at high altitudes and can be tethered or free-floating. Airships, also known as dirigibles or blimps, use lighter-than-air gases and are larger and more maneuverable than balloons. They’re especially well suited for surveillance, communications and research.
Gliders and powered aircraft can be controlled more precisely than balloons, which are sensitive to variations in wind speed. In addition, powered aircraft, which include drones and fixed-wing airplanes, can provide electricity to communication equipment, sensors and cameras.
Next-generation power
Platform stations could make use of diverse power sources, including increasingly lightweight and efficient solar cells, high-energy-density batteries, green hydrogen internal combustion engines, green hydrogen fuel cells, which are now at the testing stage, and eventually, laser beam powering from ground- or space-based solar stations.
The evolution of lightweight aircraft designs coupled with advancements in high-efficiency motors and propellers enable planes to fly longer and carry heavier payloads. These cutting-edge lightweight planes could lead to platform stations capable of maneuvering in the stratosphere for extended periods.
Meanwhile, improvements in stratospheric weather models and atmospheric models make it easier to predict and simulate the conditions under which the platform stations would operate.
Bridging the global digital divide
Commerical deployment of platform stations, at least for post-disaster or emergency situations, could be in place by the end of the decade. For instance, a consortium in Japan, a country with remote mountainous and island communities, has earmarked US$100 million for solar-powered, high-altitude platform stations.
Platform stations could bridge the digital divide by increasing access to critical services such as education and health care, providing new economic opportunities and improving emergency response and environmental monitoring. As advances in technology continue to drive their evolution, platform stations are set to play a crucial role in a more inclusive and resilient digital future.
