What impacts will the derailment and toxic chemical leak in the United States have?

• The U.S. National Transportation Safety Board (NTSB) has announced the formation of a special investigative team to determine the cause of the accident. Investigators told reporters that train crew members received an alert about a mechanical axle failure shortly before the incident. Whether human error occurred, or whether defects existed in the train or track infrastructure, remains under investigation. It is expected that this accident will result in casualties, property damage, and localized ecological disasters, triggering insurance claims, multiple lawsuits, and delayed follow-up reporting. In the future, the incident may be adapted into various artistic and literary works. • Some local residents have already filed lawsuits demanding that Norfolk Southern establish health monitoring systems in Ohio and Pennsylvania, cover medical examinations and related healthcare costs for residents within a 30-mile radius of the derailment site, and assume liability for future damages. • A 2016 audit by the U.S. Department of Transportation’s Inspector General [4] found that agency inspectors had imposed overly lenient penalties on shippers and carriers violating hazardous materials safety regulations—and had failed to refer cases for criminal prosecution, contrary to agency requirements. The U.S. Department of Transportation stated that these issues have been resolved over the past several years, and indeed the number of fines issued annually has increased; however, it remains unclear how many cases were referred for criminal prosecution. • Reports indicate abnormal animal deaths—including chickens, dogs, and foxes—hundreds of miles from the derailment site, along with human symptoms such as headaches and diarrhea. As a result, the 30-mile radius may expand. Yet some of these symptoms could stem from COVID-19 or avian influenza. Fish and frog deaths in local streams are likely attributable to vinyl chloride. West Virginia’s governor previously issued a water-safety alert for the Ohio River, although subsequent testing confirmed the water met safety standards. • Eventually, the official investigation report may attribute the accident to a combination of factors: aging or faulty equipment, insufficient maintenance, isolated operator errors or violations, and systemic safety management gaps. • Approximately one billion tons of hazardous materials are transported annually by rail across the United States—and even more via road. Roughly 10% of U.S.-manufactured vinyl chloride undergoes transportation. In 2021, North America saw approximately 20,000 rail shipments of vinyl chloride. • Since October 2022, Ohio has experienced three freight train derailments. • On February 13, 2023, a train collided with a freight truck near Splendora, Montgomery County, Texas. The truck driver died, 21 railcars derailed—including some carrying small quantities of chemicals [5]—and diesel fuel leaked from the truck. • Over the past decade, hazardous materials have spilled or leaked from U.S. trains more than 5,000 times [6], including 172 incidents involving derailments that released harmful substances. In recent years, U.S. railroads have implemented technological upgrades to improve crashworthiness and temperature regulation, retired older railcars, and reduced crude oil transport—which peaked in 2015 and has since declined—leading to an overall decline in train accident rates compared to historical levels [7]. However, derailments now constitute a larger share of total accidents: historically averaging around 10%, they accounted for nearly 25% of all U.S. train accidents in 2022. This incident may heighten public concern about rail safety and spur demands for stronger safety measures. • Certain environmental and animal welfare advocates may respond slowly—and then revisit and reiterate this event over the coming decades.

U.S. railways are privately owned—in principle, only profitable routes are built—so why is the total length of U.S. railways longer than China’s?

Operations According to data from the American Public Transportation Association (APTA), a total of 32 agencies operate commuter rail services nationwide. Some operate their own trains directly, while others outsource passenger service. Major commuter rail systems include: the Long Island Rail Road (LIRR) and Metro-North Railroad in New York and Connecticut; Maryland Area Regional Commuter (MARC) Rail; Virginia Railway Express (VRE); Metra in the Chicago region; and Metrolink in the Los Angeles area. Half of all commuter rail systems operate at least partially on tracks owned by freight rail companies; approximately 25% of total commuter rail operating mileage lies on tracks owned either by freight rail companies—or, in the case of the Northeast Corridor (NEC), by Amtrak. Before entering freight-owned track segments, freight and commuter operators sign voluntary agreements governing their cooperation, covering matters such as operating hours, track access coordination, and train frequency. Such partnerships have significantly expanded commuter rail service: the number of commuter rail systems nationwide has grown from six 40 years ago to 27 today. Using this definition, independently operated commuter rail mileage totals roughly 6,000 miles. Urban rail transit systems, naturally, operate on entirely independent infrastructure. (This goes without saying.) Adding these figures yields a total of 101,790 miles (163,815.13 km). North American railways are classified into three tiers—Class I, Class II, and Class III. Class II and Class III railroads jointly form the American Short Line and Regional Railroad Association (ASLRRA). Its introduction states: About ASLRRA Overview: Founded in 1913, ASLRRA proudly represents entrepreneurial owners and operators of short-line and regional railroads across North America. These roughly 600 small businesses play a vital role in hub-and-spoke transportation networks—typically providing the ‘first mile/last mile’ logistics links between farmers, manufacturers, and end consumers. Service Coverage: Collectively, short-line railroads operate 50,000 miles of track—nearly 30% of the entire U.S. rail network—and handle one-fifth of all railcar movements at origin or destination points across the national system. Their track mileage has grown from 8,000 miles in 1980 to today’s 50,000 miles. They serve all 48 contiguous U.S. states, reaching every corner of the country—from forests and inland heartlands to coalfields. In some states, short-line railroads control 100% of the state’s rail network; in 15 states, they operate over 50% of the rail network. They transport diverse commodities, including chemicals, foodstuffs, aggregates (e.g., gravel and construction materials), and intermodal freight. This figure is clearly an estimate. A relatively precise statistic available elsewhere indicates 10,335 miles for Class II railroads and 37,165 miles for Class III—totaling 47,500 miles.

North American Chemical Rail Traffic Rises 3.9% Year-Over-Year
